When evaluating fatigue in structural components, you can use COMSOL Multiphysics and the Fatigue Module. This archived webinar shows you how to model a mechanical shaft design and evaluate fatigue due to non-proportional loading. Time-varying loads applied to structural components can lead to fatigue failure even when the stresses and strains are not particularly high. Several add-on modules are featured here and offer important capabilities to simulate a fatigue cycle. Specific applications and example models from the Fatigue Module are shown including Rainflow counting, the Palmgren-Miner damage rule, and critical plane methods.
