Abstract

On the basis of a mathematical model of A. A. Il'yushin's theory of elastoplastic processes, numeric calculations are given for programs of experiments in the form of two-link broken strain trajectory. The results of the numeric simulation are compared with the experimental data obtained by authors on the automated test-machine SN-EVM. Delaying of vector and scalar properties is investigated. The instability of magnitude of the trace of delay as a characteristic of the material is shown.

Keywords: plasticity; complex loading; two-link trajectories; loading process; vector and scalar properties; trace of delay
