Abstract: The paper describes a method for constructing a solution to the problem of physically nonlinear deformation of transversely isotropic composite bodies, in which the stiffness of the reinforcing elements is much higher than the stiffness of the binder. A simplified model of plastic deformation is used. The technique is a synthesis of the Poincare perturbation method and the energy method of boundary states. The problems for the cube and cylinder are solved, the accuracy analysis is carried out and conclusions are formulated.
Key words: Boundary state method, perturbation method, transverse isotropy, composite materials, physical nonlinearity.
