Essay

A strain criterion for the fatigue failure of metallic materials under cyclic loading at a complex stress state has been developed. A phenomenological model is proposed as applied to the determination of the maximum levels of an additional strain hardening under strain-controlled nonproportional biaxial loading based on the material mechanical properties under static loading
