The paper deals with a general approach in stability analysis of elastic-plastic shell structures. Among all cylindrical shells under axisymmetrical loads were disscussed and analysed preferably in scientific publications because their application in engineering practice is very important. Also, spherical and conical shells of different shape were considered giving both analytical and numerical solutions. Computer methods are preferred in the solutions, because in most cases the resulting equations of stability problems are transcendental, so, the paper presents the main frames of the numerical iterative algorithms and their computer implementation. The algorithms make possible to perform a specific analysis of the considered problems, with taking into consideration possible imperfections, geometrical and material nonlinearities, boundary conditions and different loadings.
