Abstract: To analyze the process of deformation of layered structural elements from inelastic materials, an approach is proposed that makes it easier to solve the problem with complex types of loading. When it is used, the package is homogenized, based on its replacement by a plate with a homogeneous structure through the thickness, the mechanical characteristics of which are determined by identification methods based on the results of numerical experiments with simple types of loading. The results of solving the formulated problem of cyclic tension of three-layer plates with linearly elastic outer layers and a viscoelastic middle layer are presented, obtained by the standard and proposed method.

Keywords: fiber reinforced plastic, viscoelastic strain, irreversible creep strain, numerical experiment, identification.
