Tiivistelmä

In this work, a unified low- and high-cycle fatigue model based on continuum
mechanics is developed. The high-cycle part of the model is based on the concepts of a moving endurance surface in the stress space with an associated evolving isotropic damage variable. The low-cycle part of the model is formulated as a traditional nonlinear isotropic and kinematic hardening J2-plasticity model. The LCF- and HCF-models are connected via the damage evolution equation. Performace of the model is demonstrated with a numerical example.
