摘要：

We consider a method for calculating the residual stress-strain state of an explosion-loaded metal in the case of nonuniform geometry of shock-wave flows with the use of a rather realistic viscoelastic-plastic model of the medium. We have derived relations that allow one to describe the configuration of the "stress-strain band" created by explosive loading in a metal and to determine the parameters of this band. Calculation results for plates made of low-carbon steel have been compared with experimental data. Satisfactory agreement has been attained. Ways for improving the calculational procedure proposed, in particular, ways for taking into account the metal viscosity versus the deformation velocity, have been proposed.
