For development of models of strength and compressibility of metals in wide range of pressures (up to several megabar) and strain rates u e ∼ 1 ÷ 10 8 s −1 ,t he method of dynamic tests is used. Since direct measurement of strength is impossible under complicated intensive high-rate loading, a formal model is created at first, and then it is updated basing on comparison with many experiments, which are sensitive to shear strength. Elastic-plastic, viscous-elastic-plastic and relaxation integral models became nowadays most commonly used. The basic unsolved problems in simulation of high-rate deforma- tion of metals are mentioned in the paper. |
