In this paper, the calculation results are presented, on the basis of which the influence of the load amplitude on the stress-strain state of a cylindrical shell is analyzed. The dynamics of elastoplastic deformation of a circular cylindrical shell of infinite length under pulsed axisymmetric loading are described by the equations of the Kirchhoff – Love theory and the theory of flow. The problem was solved by the finite difference method, and the accumulation of plastic deformation was taken into account using iterative refinement. The calculation results are made for steel and aluminum shells. The influence of a change in the geometric and physical parameters of the shell, as well as the amplitude and shape of the pulse load on the dynamics of the structure, is studied. We also studied the change in the mechanical properties of the material on the stability of calculations and on the residual deflections of the walls of the structure.
