MULTIAXIAL FATIGUE LIFE CRITERIA AND MICROSTRUCTURE MODELING OF METALS

摘要：

Years of active research since the end of the 19Ih century lead multiaxial fatigue strength methods to a mature state.However,some key experimental features are still not well understood and captured (nonproportional loadings,non-linear damage accumulation under variable amplitude loadings for example).This paper proposes to analyze some fundamentals of well known multiaxial fatigue life prediction criteria in the HCF domain in the light of FEA results using polycrystalline plasticity modeling.The local stress state developing in FCC artificial microstructures under complex loading has been investigated.The heterogeneity of the local mechanical response will be discussed .
