【 摘 要 】

A method for calculating problems of uniaxial shock-wave loading of material is proposed in this paper. The method is based on Cabaret finite difference scheme. The mathematical model of the impact loading is described in Lagrangian formulation in the one-dimensional case. The task is approximated by the scheme. A comparison is made with the analytical solution. Verification of the approach is carried out on experimental data.
