Abstract
A novel energy-based multiaxial fatigue criterion was proposed considering the effect of normal strain energy and shear strain energy. The difference of contributions of both the normal strain energy and shear strain energy on the failure of materials was identified by introducing the stress-path-dependent energy weight coefficient. A newly defined non-proportionality based on the stable hysteresis loops was introduced to the criterion considering the non-proportionality additional hardening behavior. Most of the coefficients can be determined by the monotonic tensile test which gives more opportunities for the applicability and feasibility of the new criterion in engineering practice. The performance of the new criterion was approved by comparing the predicted and tested life of SS304 under various multiaxial loading paths.
