In this work, an extension of a previously developed continuum based high-cycle fatigue
model is enhanced to also capture the low-cycle fatigue regime, where significant plastic
deformation of the bulk material takes place. Coupling of the LCFand HCF-models is due to
the damage evolution equation. 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. Damage evolution in the low-cycle part is determined via plastic …
