Prediction of the effect of plastic-strain stabilization under cyclic deformation based on the structural‒temporal approach

Abstract

On the basis of modification of the relaxation model of plasticity developed previously for the case of single loading, a new model of cyclic deformation is formulated. It is shown that the introduction of only one constant time parameter dependent on the material structure makes it possible to compose a simple calculation scheme of accumulation of residual strains under multiple cycling of samples.
