Abstract
The possibility of using the multitime model of the endochronic theory of plasticity for calculating the complex elastoplastic deformation of cyclically stable materials, for example, steel 45, is discussed. It is shown that defining relationships constructed on the basis of analysis of data derived from the simplest experiments can be used to describe the behavior of materials under extremely complex load regimes, including loadings with curvilinear three-dimensional strain paths.
