Abstract: The process of nonlinear elastoplastic deformation of a cylindrical shell under influence of pulse and hydrodynamic loadings is numerically investigated. Calculations of shell were carried out for elastic and elastoplastic models on the basis of the Kirchhoff-Love and Timoshenko theories. The influences of the loading duration, its intensity and amplitude, as well as geometrical and mechanical characteristics of the structure on the nonstationary behavior of the hydroelastoplastic system are analyzed.

Key words: cylindrical shell, Kirchhoff-Love theory, Timoshenko theory, elastoplastic solution, numerical solution.
