Modeling of elastoplastic steel deformation in two-link broken trajectories and delaying of vector and scalar material properties


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.
