Advanced Failure Analysis of Materials

Course Description

This advanced course presents theories for preventing/mitigating the failure modes that are most frequently encountered in mechanical engineering. These include high-cycle fatigue, low-cycle fatigue, stress concentration, fracture, creep, fretting, fretting fatigue, shock and impact, buckling, wear, residual stresses, etc. This course shall cover such important design tools as: linear fracture mechanics, the various widely-used rules for predicting fatigue strength, models for predicting crack growth, the most important criteria for yield failure, stress wave, and so forth. Cases studies (such as the effects of residual stresses on the failure of railway rails) that involved the various failure modes shall be discussed, with an eye to reinforcing the students’ ability in applying the various theories.
