Abstract

The spatial problems of interaction of elastoplastic structures with the detonation products in Eulerian variables using overset grids are considered. For numerical simulation, the modification of the S.K. Godunov scheme of increased accuracy is used, the same for both gas-dynamic and elastoplastic flow. On the moving contact boundary of the gas with the deformed body, the exact solution of the Riemann’s problem is used. A defining system of three-dimensional equations of gas dynamics and a compressible elastoplastic body is presented. An algorithm for numerical solution is described. The results of three-dimensional calculations of acceleration of elastoplastic bodies of different shape by product of detonation are presented. The essential influence of the position and the deformable shape of the body on the process of loading and deformation are demonstrated.
