Abstract

Two approaches to identification offracture surfaces in the problems of mathematicalsimulation of the processes of high-speed interactionof elastoplastic bodies are suggested. On the basis ofthese approaches, solutions to the problems ofprojectile penetration into semi-infinite targets,split and shear fracture of finite-thickness platesare presented. The results of numerical simulation arecompared with experimental data, and a good agreementboth in the final parameters and in dynamics of theprocess is obtained.
