A code to solve 1D continuum mechanics problems is described, allowing to account the following physical processes: gas dynamics, elastoplastic deformation on the basis of Prandt1Reiss plastic flow laws, explosive detonation, breakoff and radial fracturing, diffusionapproximated heat conductivity. Finite difference walkthrough pseudoviscosity method ("CREST"scheme) is used for numerical solution of the gas dynamics system. Radial fracturing, evaporation, melting and explosive detonation are realized in the program through the equation of state. The program is blockstructured and has dynamic memory allocation. The program computer complex linking is made depending on the type of symmetry of the problem being computed. Problem capabilities are demonstrated by computing 6 test problems.
