Option | Description |
Loading | One of the main inputs for a fatigue life estimation is the file that describes the loading environment to which the component or assembly is to be subject. Three types of loading file can be specified: Time History which normally means a single parameter .dac time history or .pvx peak valley file. This can be a measured strain time history or a strain time history extracted from FEFAT. Range Mean Matrix which normally means a rainflow matrix file with a .cyh extension. Constant Amplitude which requires the user to enter individual values of Amplitude and Mean Value. For all file types the data should preferably be in units of Microstrain (uE). If they are NOT then a calibration file that contains the appropriate conversion factors should be supplied. |
Calibration File | Any other system of units such as those associated with load or force etc., can also be used provided that the appropriate conversion function is supplied by means of a calibration file. Calibration files have a ASCII format. A calibration file must have the following structure: Input on X and output on Y, where output must be in the default internal units,i.e. microstrain, and input can be any user unit. The data pairs must be entered X (input) followed by Y (output), with one pair per line. A space is a sufficient delimiter between X and Y values. The calibration should increase monotonically from the smallest values to the largest. If necessary MCLF will linearly extrapolate beyond the ends of the calibration. Internally, MCLF interpolates between specified values. The units of both the input and output should be specified. In the case of an ASCII file, these units are defined through the use two comment lines (lines preceded by the # character) at the beginning of the file, e.g. #input=Newtons #output=MICROSTRAIN -1000 -100 0 10 1000 150 In this case input in Newtons is related to output units of microstrain. As a guide note that: Microstrain = absolute strain x 1E6 Microstrain = per cent strain x 1E4 Microstrain = per mil strain x 1E3 |
Strain State | Axial Loading: Typically, at the surface of a component, the stress normal to the surface is zero and conditions of plane stress are said to prevail. Under these circumstances (and if the maximum principal strain remains relatively stationary throughout the loading sequence), it is appropriate to use uniaxial properties directly. Plane Strain Loading: If the component thickness is large relative to the notch root, and transverse contraction is effectively prevented, then plane strain conditions prevail. Typically, such conditions may be found on the surface of a thick-walled cylinder, or very thick sections. The triaxial stress state, found in plane strain, effectively alters the uniaxial cyclic stress-strain curve in the first principal direction. This modified curve is obtained by noting that the transverse strain and the stress normal to the notch surface are both zero and applying the Hencky plastic flow laws. If no entries are found in the material data base, then in the correction procedure an elastic Poisson's ratio of 0.3 and a plastic ratio of 0.5 are assumed. Shear Strain: Conditions of pure shear arise when the biaxiality ratio approaches -1. A typical situation is of a shaft loaded in torsion. If the shear strain state is selected, MCLF will expect the input loading to be in terms of a shear strain history (usually the signed absolute maximum). Such histories are obtained through the use of strain gauge rosettes together with the appropriate outputs from the stress-strain analysis module, MSSA. The uniaxial material parameters will be automatically adjusted to account for this strain state. |
Strain type | The strain input to MCLF can be in one of two forms. The first is measured strain, which was the default for this program in previous versions. This strain is assumed to lie on the cyclic stress-strain curve, whereby if yield has occurred then the strain will change in a non-linear way as load increases. The strains will be in this form if a strain gauge has been used. Alternatively, the strain may have been calculated theoretically, from classic elastic theory or from finite element analysis. In this case the strain is usually linear elastic, and MCLF must use a different method to calculate local stress and strain. |
File Name | The name of the loading file should be entered in this field. Note that if Loading = Time History then MCLF expects a single parameter .dac or .pvx file to be entered. If Loading = Range Mean Matrix then a .cyh file is expected. File names with other extensions can also be typed in this field. |
Amplitude and Mean | Multiple values of amplitude OR mean can be entered. For example entering (1000,5000,500) will calculate values from 1000 to 5000 inclusive at intervals of 500. Entering 1000,2000,3000 (without the brackets) will calculate values at 1000, 2000, and 3000. MCLF will run the calculation for them all (although as only one multiple analysis criteria is allowed per run no other criteria can be multiple). “BACK” can also be entered, in which case the required life must be entered and MCLF will calculate the amplitude and mean required to achieve that life. The Show button on the right of the header bar can be used to display the values that will be processed. |
Time Window | Not all of the Loading Time History file has to be used in the calculation. If only a part of the file needs to be used then the start point and end point can be specified in the Time Window. The default is to use all of the time history file, which is why the defaults are START and END. If a part only is to be used then clear the fields and enter the values, i.e., 10 in the Start field and 1000 in the End. Alternatively the syntax START+n and END-n' where n is a number of units (e.g. seconds) from the start of the file and n' is a number of units before the end of the file. START and END are usually recorded in the header area of the input file. Please note that start is not necessarily zero. |
Calibration file and units | The use of a calibration file to convert input loading units to microstrain has been specified. In this field the name of the file which contains the calibration, in the appropriate format, must be provided. As a default, calibration files are assumed to have the file name extension .cal and so, the required file may be selected by entering its name directly without this extension. In the units field, enter the units of the input, X, half of the calibration file. This can be any text string and is used only for reporting the units back to the user. For Scale Factor, Offset, and Cycles Gate: if multiple entry is employed then a Damage Matrix, Rainflow Matrix, or Cycles File will NOT be produced, although MTPD will plot the results and will allow them to be stored as a hardcopy plot file. |
Scale Factor | The scale factor is an amount by which the loading history or matrix will be multiplied. Multiple scale factors can be entered separated by commas or as, for example entering (-500,1000,50) in the field will scale from -500 to +1000 inclusive in steps of 50. BACK may also be entered in which case MCLF will calculate the scale factor needed to achieve the required design life. |
Offset | The offset is a value added to the results file(s) after the scale factor has been applied. For example, if the original loading file had an amplitude of 10 and a scale factor of 30 then the result (300) would then have the Offset applied. If the offset was -5 then it would be 300-5, or 295. |
Cycles Gate | The gate is in effect, a filter that speeds processing by filtering any small cycles that are unwanted (for example signal noise). The gate value should not be set too high or it will filter out relevant parts of the signal. Any signal smaller than the gate value specified in this field will be ignored in the life calculation. Multiple gate values can be entered using the same syntax as the example given for scale factors (above). No results file will be saved if a multiple analysis is carried out. A multiple gate analysis can be used to assess the gate value so that the user can choose the gate threshold that just fails to remove genuine damaging events. The gate threshold value is sensitive to changes in material and Kf. Also if a signal is scaled up by 2, the gate is NOT automatically scaled up by 2, the user must manually scale up gate. |
This Input File is Equivalent to... | The fatigue analysis to be carried out is through the use of a either a time series, range-mean matrix or a sequence of peak valleys. The results will normally be presented in the form of the number of repeats of these series to failure. An equivalent unit, such as miles, laps, hours, etc. can be attached to the input loading file so that results can be presented in the form of miles, laps or hours to failure. |
Option | Description |
Method | The elastic stress concentration factor, Kt, is the ratio of the maximum stress at a stress raiser to the nominal stress computed by the ordinary strength- of-material formulae, using the dimensions of the net section. It can be used to account for the presence of a notch within a component or structure. The magnitude of the Kt required depends on the nature of the notch and its geometry. Values of stress concentration factors can be obtained from standard works such as: R.E Peterson's 'Stress Concentration Factors', John Wiley & Sons, Inc. 1974. Alternatively use can be made of the Time Correlated Damage - (MTCD), 1072 module. It is well known that small notches have less effect in fatigue than is indicated by Kt. This has led to the idea of a fatigue concentration factor, Kf, which is normally less than Kt, being introduced and being used to replace Kt within Neuber's rule. Kf is related to Kt according to: Kf = 1 + (Kt - 1) / {1 +  } p' is a material constant dependent on grain size and strength and r is the notch root radius. If Kf is not known, then estimate the theoretical stress concentration factor, Kt, and select the calculate option, otherwise select the direct entry option. |
Kf vs. Kt | If Kf or Kt are being entered directly other fields, such as notch root radius, do not appear. Single or multiple values of either Kf or Kt may be entered. Alternatively, the word back, or BACK, may be entered in which case MCLF will request the entry of a desired life and then will calculate the Kf required to achieve that life. Note that only a single arithmetic operation between delimeters (comma or space) can be undertaken, so 3+3/2 would cause an error. |
Notch Root Radius (r) and Notch index (q) | Enter a value for the notch root radius in mm. A value will enable MCLF to calculate q and display it in the Notch Index q field. The notch sensitivity index, q, has been found to be a function of both material and notch radius. Neuber has defined q as: q = 1 / {1 + √(p'/r)} where: p' is a material constant dependent on grain size and strength and r is the notch root radius. The parameter p' has units of distance, mm, and for a medium strength steel with a UTS of 750 MPa has a value of about 0.1 mm. The notch index q can only be calculated for steels that have a UTS of 50 - 250 ksi (about 340 - 1700 MPa). |
Additional Kf | The fatigue strength of a component can be reduced further as a result of metallurgical defects such as inclusions or porosity. This field allows such additional Kf effects to be included in the life calculation. The number entered here will be multiplied by the value of Kf above, and the resultant combined value used in Neuber's rule. When the multiplication has been done the calculated Kf is displayed in the Calculated Kf field. When setting up a new Job the next data to be defined is the Output Definition screen (also called the Results Setup screen) which is explained below. |

Option | Description |
Histogram type | If none is selected here, then no histogram damage file is generated. If Input Units is selected then a damage histogram file will be generated with the same units as the input file. Selecting Nominal uE or Local uE will produce histograms scaled in strain units, either nominal elastic or local elastic-plastic ones respectively. A histogram with the axes scaled in terms of strain amplitude and maximum stress is produced by selecting the SWT option. The number of bins can also be specified. |
Damage Units | The units of the damage displayed in each cell of the damage matrix can be specified. The damage can be output as actual damage values, as percent damage or damage normalized to 1.0. Select the required units. |
Cycles file | In the case of a single shot fatigue life estimation, an output results file can be generated. This file contains details every cycle extracted by the rainflow algorithm, in terms of its nominal stresses and strains together with the associated fatigue damage. The cycles file may be viewed and searched using the list cycles option on the display results menu or postprocessed using the MCYL module. |
Histogram Limits | The limits of the rainflow and damage matrices can be automatically determined to match the limits of the data, or they can be 'User' specified. If they are user-specified then the range and mean minimum and maximum fields (described below) become active. |
Range Minimum/ Maximum | The range limits can be manually specified in these two fields in the units specified. |
Mean Minimum/ Maximum | The mean limits can be manually specified in these two fields in the units specified. |
Hysteresis Loops and Number of Loops | In the case of a single shot analysis, an output file which contains the 'n' largest hysteresis loops, i.e., stress-strain cycles, extracted by the rainflow algorithm can be generated. The contents of this file may be displayed graphically by selecting the plot loops option on the display results menu or by invoking the X-Y plotting module, MTPD. The file created will have the same generic name as given to the cycles and damage matrices but its extension will be .slp. Select Yes or No for this file. The number of loops to be saved in the output file can be specified here. Note that the default is the 5 largest loops. Any positive number can be entered. Use the display loops option to view the loops. |

Option | Description |
Input File Name | When this option's mask is first run only the Input File Name field is displayed. The user must tell MCYL the name and location of the cycles file to list. This file must be a standard cycles file from the fatigue analysis section or from the signal classification section. By default, MCYL expects to find any input data files to be resident in the user’s directory. Probably the easiest method of entering input file names is to use the pick list facility. This also enables other drives/directories to be accessed. If a file name is entered without an extension then the default extension .clf will be given to the file name entered. A default file name may also be given in the question window. When the Input File Name field is filled the other fields become active. They are explained below. |
Listing | In a critical location analysis, results are produced for the nominal location, and at the critical (local) location. Because of limited listing space, only one of these sets of results may be listed at one time. Therefore select either 1 or 2. |
Gate Value (also applies to Damage Gate) | A gate may have originally been applied during the analysis to limit the calculation to large cycles only (setting a gate value is a method of reducing signal noise). It is possible to increase the original value with a higher gate value to further limit the listing. The gate must be a range value in the units of the file listing. For example in a stressed based file the gate value should be in MPa, whereas for strain based the units should be uE. |
Display Type | The cycles may be shown in Max/Min format (where the peak and trough values of the cycles are displayed) or Range/Mean (where the range is the distance between max and min and the mean the average of the max and min.) Enter the value 1 or 2. Alternatively, the strings MAX and RANGE are also recognized. |
Output Destination | The cycles file data may be displayed at the user’s terminal by selecting S for Screen, or written out to a list file by selecting F for file. If File is selected then an additional Output File Name field must be filled. The default output file name is that of the input file but with a .lst extension. The default file name can be edited by the user (to avoid overwriting an existing file for example). |
Output File Name | Enter a file name to which the data should be sent. The default extension for the file is .lst (see Output Destination above). The output file contains header information and a complete listing of the data in the cycles file. |
Option | Description |
Input File Name | A cycles file from FEFAT, MCLF or MSLF should be input here. A damage histogram input field is also available (MCYL knows the source of the input file by reading it's header). The damage histogram field is optional. |
Generic Output Name | Type the name of the file (or files if a damage file is also to be created). The default is to copy the Input File Name although this may require the input file to be overwritten. |
Cycles Matrix Type | MCYL is able to form up a range-mean matrix from a cycles results file in terms of either stress or strain. Toggle the appropriate option into the field. MCYL will then display the limits of the largest and smallest cycles present in the cycles results file and prompt for the following: |
Minimum Range Limit | For the purpose of scaling the histogram the range of the smallest cycle to be represented in the histogram must be entered in physical units (usually microstrain). If there are any cycles smaller than the minimum range specified, then those cycles will be excluded from the histogram. However, a warning message will appear and a note made in the note book. |
Maximum Range Limit | For the purpose of scaling the histogram the range of the largest cycle to be represented in the histogram must be entered in physical units (usually microstrain). If there are any cycles larger than the maximum range specified, then those cycles will be excluded from the histogram. However, a warning message will appear and a note made in the note book. |
Number of Columns | For the purpose of scaling the histogram it is possible here to specify the number of classes (bins) into which to classify the cycle means. Any integer number up to a maximum of 128 (the default) may be entered. |
Number of Rows | For the purpose of scaling the histogram it is possible to specify the number of classes (bins) into which to classify the cycle ranges. Any integer number up to a maximum of 128 (the default) may be entered. |
Minimum Mean Limit | For the purpose of scaling the histogram the smallest mean value to be represented in the histogram must be entered in physical units (usually microstrain). If there are any cycles whose mean values are smaller than the value specified, then those cycles will be excluded from the histogram. However, a warning message will appear and a note made in the note book. |
Maximum Mean Limit | For the purpose of scaling the histogram the largest mean value to be represented in the histogram must be entered in physical units (usually microstrain). If there are any cycles whose mean values are greater than the value specified, then those cycles will be excluded from the histogram. However, a warning message will appear and a note made in the note book. |
Option | Description |
Cycles File Name | Specify a cycles histogram file in this field, for example one generated in the Form a Cycles Matrix option. The default extension is .cyh but other compatible file types can be typed with their extension. This field may be left blank if only a damage histogram file is to be listed. |
Damage File Name | Specify a damage histogram file in this field, for example one generated in the Form a Cycles Matrix option. The default extension is .dhh. This field may be left blank if no damage histogram file is to be listed. |
List Zero Bins | List Zero Bins = No, will filter out from the listing any data entries that contain zero cycles (and therefore contribute nothing to the analysis). If this is set to NO it will ONLY apply to the cycles matrix NOT a damage matrix, should one be included in the processing. |
List Type | 3D is a normal 3D histogram plot, 2D = Range plots the sum of the X-axis values, 2D = Mean plots the sum of the Y-axis values. |
Bin Location | The matrix files hold values in mean or range bins. The maximum of the bins can be used for the listing, or the mean of the bins (mean is (maximum-minimum) /2). |
Damage Gate | Setting a gate at any value will filter out any data entries with a value LESS than the gate. Leaving this field blank will filter out nothing. |
Destination - Screen or File | If the input file(s) are to be listed to screen select Screen. To save them to disk select File. They will be saved in the current directory. |
Option | Description |
Input File Name | This field should contain the name of the cycles file that is to be converted to Excel text (.txt) format and saved on to disk. |
Output File Name | By default this is the same as the Input File Name not with a .txt extension. However any valid name and extension can be specified here. |
Output Format | The program can create two types of file. In the first case, all the data is written to the file, including header and label information. In the Raw Data option, only the matrix data is written. |
Label Data | The data is normally output to the tab separated file without labels and totals. To add labels and totals to the data, answer Yes to this question. |

Option | Description |
Output File | Enter the name of the output file. The default extension is .dam. This file is in .dac format. |
Output File Type | Output damage files can have either of two formats. In the first, the single value format, the absolute damage associated with each turning point, half for each cycle or reversal, is written to the output file at the same point in time it occupied in the time series file. Non turning points have zero damage ascribed to them. In the second format, the damage is accumulated as it occurs and so provides insight into the rate of damage accumulation. |
Start At | MTCD uses a single pass algorithm to accumulate fatigue damage. As a result, analysis can commence at the beginning of the loading sequence, instead of at the largest excursion, and so provide a more accurate distribution of damage within the time series. For compatibility with MCLF and FEFAT, MTCD has been provided with the option to commence analysis at the largest absolute strain excursion. When run in this mode, MTCD will provide values of total damage similar to those calculated by MCLF, if not, the values will be slightly different. |
Note: | If any parameters are changed the Recalculate option must be run for the changes to take effect. |
