A method is proposed for calculating critical loads and studying the precritical state for plastic shells. A comparison is made with well known theoretical and experimental data. The stability of elastoplastic systems has been examined. Here, however, we use equations in displacements, where equations of mixed form were used. We consider the nonlinear precritical state of cylindrical shells and propose a procedure for finding their critical loads. The distinctive features of the stress-strain state are analyzed and the critical loads are compared with known theoretical and experimental data. We presented a procedure for obtaining nonlinear equilibrium equations and linearized equations for elastic shells of revolution. We generalized the procedure to shells that deform beyond the proportionality limit.
