Abstract
The article presents the results of a comparative analysis of the deformation process in convex-concave and trapezoidal strikers using computer modeling by the finite element method in the Deform program.In both designs, two variants are considered -with an equal and unequal ratio of the protrusion to the depression.For comparative analysis, equivalent stresses and strains, energy -power parameters are considered.Also, on the basis of computer modeling, the analysis of the microstructure evolution during the deformation in convex -concave and trapezoidal strikers was carried out.In the course of computer modeling, some advantage of the design of convex -concave strikers in comparison with trapezoidal strikers was proved.
