RESEARCH GOALS: Mr. Martinez and the Instituto Politecnico Nacional are working to increase the reliability of prediction life using stochastic analysis.

METHODS:

• Study scatter in durability tests: material properties and loads.
• Evaluate stresses with statistical tools and linear and nonlinear damage models.
• Propose a new model for improving the accuracy of life prediction.

MSC RESEARCH ASSIST AWARD: Mr. Martinez and the Instituto Politecnico Nacional were awarded MSC Fatigue to evaluate steering knuckle and mounting bracket part components by applying different tracks with variable amplitude loads.

BIO: Mr. Martinez holds a MSc and B.S. in Mechanical Engineering from the National Polytechnic Institute. He has five years of experience as a Developmental Engineer for the Mexican Petroleum Institute (IMP) developing tools and equipment for onshore and offshore petroleum operations. He has also worked as a CAD/CAE engineer and a test engineer for Passive Safety.

Mr. Martinez is currently working as a test engineer, specializing in fatigue testing at Volkswagen de Mexico. He has participated in National and International Congresses and is a co-author of a patent for the petroleum industry.

RESEARCH UPDATE:

April 2013

• Mr. Martinez is evaluating estimated relationship to estimate the S-N curve based on ultimate strength.
• He is also performing FE simulation of the steering knuckle to preduct the life with the estimated S-N curve.

January 2013

• Mr. Martinez has analyzed mechanical properties of materials.
• He is currently analyzing the test results to predict the S-N curve in the High Cycle Region.
