A method is developed for analysis of the elastoplastic stress-strain state of laminated shells of revolution under axisymmetric
loading. The shells are made of isotropic and transversally isotropic materials with different moduli. The method is based
on the Kirchhoff-Love hypotheses for the whole laminate, the theory of deformation along paths of small curvature (for isotropic
materials), and the theory of elasticity with different tensile and compressive moduli (transversely isotropic materials).
The problem is solved by the method of successive approximations. Numerical examples are given
