The stress condition of a metal-polymeric three-layer beam of rectangular cross section with stepped variable thickness of one of two stiff shells is considered. To describe kinematics of asymmetrical over thickness core pack the hypotheses of the broken normal are accepted. Stiff shells deformation is circumscribed by correlations of small elastic-plastic deformations theory, filler is elastic nonlinear. A system of equilibrium equations and its analytical iterative solution in terms of displacements have been derived. Numerical results were adduced.
