ANSYS Fatigue Analysis

Prerequisites: 

Proficiency with performing structural analysis in ANSYS Mechanical.

Description:

This course provides an introduction and overview of fatigue theory and how it can be applied within the Fatigue Tool in ANSYS Mechanical to perform life prediction of structures subjected to cyclic loading.

Fatigue is a failure mechanism where a material subjected to a repetitive stress will fail at a stress much lower than what is required to cause fracture on a single application of the load.  Fatigue failure typically occurs without any obvious warning in engineering metals. 

General fatigue definitions and theory will be presented in the course, including Stress Life and Strain Life fatigue approaches, which model high cycle and low cycle fatigue, respectively.  The course will review the different ways of defining cyclic loading within the ANSYS Fatigue Tool, including constant amplitude, non-proportional, and history loading.  Input of fatigue material property definitions within Workbench will be presented.  Mean stress corrections and other adjustments to the fatigue calculations to account for real world conditions will be addressed.  The particular case of modeling fatigue in welds will be discussed.

Course workshops will be included that address the features described above.
