Asymptotic modeling of nonlinear wave processes in shock-loaded elastoplastic materials

Nonlinear wave processes in shock-loaded elastoplastic materials are modeled. A comparison of the results obtained with experimental data and numerical solutions of exact systems of dynamic equations shows that the model equations proposed qualitatively describe the stress-distribution evolution in both the elastic-flow and plastic-flow regions and can be used to solve one- and two-dimensional problems of pulsed deformation and fracture of elastoplastic media.
