Abstract. For development of models of strength and compressibility of metals in wide range of pressures (up to several megabar) and strain ratesε ∼ 1 ÷ 10 8 s −1 , the 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 deformation of metals are mentioned in the paper.
