We study the quality of simulations related to high-intensity impacts which may lead to critical stresses and destruction of solids. The simulations are done under conditions close to applicability limits of models built with the use of local thermodynamic equilibrium principle. We use Prandtl-Reuss approach to elastic-plastic flows. Numerical experiments are performed using explicit monotonized techniques. The following models are considered: (a) Mises model (check of the integral load at any point); (b) Tuler-Butcher model (check of the incubation time); (c) Hashin model (check of stresses with respect to their ultimate values). We discuss the results of solving model problems: fracture in fiberglass suffered to high-energy loads. This work was supported by the RSF (project No. 16-11-00100p). [ABSTRACT FROM AUTHOR] |
