Abstract: A new simple two-parameter multi-axial fatigue failure criterion is proposed, which is focused on the engineering application. The proposed multi-axial fatigue failure criterion is based on shear strain and normal strain, and then focused on cycling additional hardening normal stress is selected to replace normal strain. The damage degree is assumed to be linearly accumulated. The larger one of the two parameters determined the orientation of critical pane, and the linear combination of the two parameters is considered to be simple and convenient to predict fatigue life.

Keywords: Low-cycle fatigue, fatigue damage accumulation, critical plane approach, two parameter
