Studies on Basic Mechanisms of Structural Fatigue.

Abstract

Cumulative damage procedures based on a local stress-strain approach which includes an adequate description of metal processing, plastic deformation history and resulting residual stresses, can adequately predict fatigue for uniaxial stress at temperatures where metal deformation is time dependent. The extension of these procedures to biaxial stressing and elevated temperatures is possible for limited cases but much remains to be done before general applicability is possible. Models for reversed plastic deformation capable of describing structural plasticity have been successfully applied to several metals and geometries. Load history characterization by generalized models is on the other hand applicable only in a few restricted cases.
