Fatigue life predictions by integrating EVICD fatigue damage model and an advanced cyclic plasticity theory

摘要: Abstract An event independent cumulative damage (EVICD) fatigue prediction model was previously developed for the under general multiaxial stress state and loading conditions. The takes plastic strain energy as major contributor to damage. application of EVICD does not require a cycle counting method random loading. In current effort, derivations were made explicitly directly relate material constants in parameters Manson–Coffin equations cyclic stress–strain curve material. addition, an advanced plasticity theory implemented determination detailed response that required input model. Three metallic materials used demonstrate capability modified predictions lives different results show can provide life close agreement with experimental observations.
