| Abstracts: | Overview of the problem of constructing of dynamic stress-deformation diagrams considering friction and radial inertia by the direct impact method and results of a numerical study of friction influence on the strain – stress state of tablets-specimens and forming in the process of loading for large deformations are presented. The inaccuracies of neglect frictional forces depending on the friction coefficient, the degree of strain, hardening and sensitivity to rate of material deformation (12X18H10T steels, 09G2S and C1 lead) are estimated.
