Summary

Experimental and calculated approach to the study of deformation and strength characteristics of elastoviscoplastic materials by direct impact method is proposed. The method involves determining integral characteristics of the deformation process of hat-shaped specimens in tension using a direct impact method and numerical solution of the axisymmetric problem. The results of experimental and theoretical study of the deformation and failure of hat-shaped specimens in the presence of stress concentrators are obtained. The direct impact method allows increasing strain rates and strains, and covering a range of low strain rates. The influence of the form of the striker on the process of impact tension of hat-shaped specimens is studied, and the stress-strain state in the hat-shaped specimens is investigated.
