Residual-compressive stresses can pump fatigue strength

摘要

Estimating fatigue strength in components and assemblies is a frequent engineering task. Doing so is critical to judging a component's durability for both its operational life and that of the equipment in which it is used. That much is common knowledge. But did you know that FEA can indicate how much cold work might improve a part's fatigue strength? It can. But lets start by examining material properties.
