Material Library
By choosing the Materials toggle located on the application selections for MSC Patran, the Materials form appears. When creating materials, several option menus are available. The selections made in this option menu will determine which material form is presented, and ultimately, which SAMCEF material will be created.
The following pages give an introduction to the Materials form, followed by the details of all the material property definitions supported by the MSC Patran SAMCEF Preference Guide.
The .MAT is used (in most cases) to define the material data for elements. This places a restriction on the element types supported by MSC Patran SAMCEF.
Materials Form
The Materials form shown below provides the following options for the purpose of creating SAMCEF materials
The following table shows the allowable selections for all options when the Action is set to Create and the Analysis Type on the Analysis Preference form is set to Structural. The various options have different names, depending on previous selections

Thermal
Defined Properties Using Fields
Properties which depend on temperature, strain and strain rate can be input using tabular and
general fields.
The function expression for general fields is as follows:
[polynom (E0|E1|E2|E3|E4|MIN|MAX|variable) ]
where
E0, E1, E2, E3, E4 are polynomial coefficients
MIN and MAX specify the valid range of the function
Variable may be ’T, ’e, or ’er.
