Abstract—Three material lifetime models are compared within the framework of the hypothesis of accumulation of residual strains. The models are based on the Ramberg–Osgood law, an alternative empirical law, and a so-called theoretical law constructed from the solutions of various differential equations in linear and nonlinear sections in a stress–strain curve. Postulating a linear section in a stress–strain curve is shown to automatically leads to the fact that the endurance limit is determined by the point of proportionality limit.
