摘要: The numerical approach, proposed by us in the accompanying papers, is applied here to simulate plastic response of a 2D idealized elasto-plastic body under conditions loading with constant strain rates. Various kinetic and structural aspects flow are extensively studied. results simulations reproduce remarkably well various common features solids, such as softening, rate pressure temperature dependences at constant-strain-rate loading. Direct comparison obtained for model solids different initial states shows that character transients strongly affected degree disorder.
