Metal failure effects predicted accurately with a unified and explicit criterion

Abstract A new criterion for predicting metal failure effects under cyclic loading conditions is derived from an innovative elastoplasticity model established most recently. As compared with usual approaches, novel results this are presented in four respects: (i) both low and high cycle fatigue can be simultaneously simulated a unified direct manner; (ii) cumbersome trial‐and‐error procedures identifying numerous unknown parameters bypassed; (iii) time‐consuming numerical not involved treating responses processes; and, the first time, (iv) data sets matched various cases of stress ratio. Numerical examples show that predictions accurate agreement test data.
