Durability 101: Don’t get tired of Fatigue

Many parts fail from fatigue—the repeated cycling of the load, which causes failure even though the calculated stresses are well below a normal allowable stress value such as the yield strength. Instead of designing to an arbitrary factor of safety, you can use your simulation analysis to perform a fatigue analysis. Based on the cyclic loading scenario that you provide, Autodesk Nastran In-CAD software will determine the number of cycles to failure or the damage. This session will discuss the options available for the fatigue analysis, the meaning of the input, and the interpretation of the results. This session features Nastran In-CAD.
