How to Predict the Fatigue Life of Welds

February 20, 2020

After an introduction to the welding process and weld geometries, we compare the nominal stress method, notch stress method, and hot spot stress methods for predicting the fatigue life of welds.

Modeling Fatigue Failure in Elastoplastic Materials

October 28, 2016

One example of fatigue failure? Bending a metal paper clip back and forth until it eventually breaks. Learn how to model this type of behavior in elastoplastic materials using COMSOL Multiphysics®.

How to Model Contact Fatigue in COMSOL Multiphysics®

August 4, 2016

Contact fatigue occurs when two parts in contact experience a time-dependent contact pressure. Learn how to model this structural phenomenon in COMSOL Multiphysics®.
