circular and annular plates, rigid-plastic materials, explosive load, W. Prager model, a linear hardening, metallurgy designs.

For polymetallic circular and annular plates of plastic material with linear hardening developed a method for solving problems of dynamic deformation when subjected to intensive loads explosive. As the physical laws of deformation model is used for the linear B. Prager hardening materials with piecewise linear potential Cod. As examples, the problem of the deformation of the ring free on the domestic circuit and solid plate in the case of hinged support on the external circuit.
