On a Method for Solving Inelastic Deformation Problems of a Laminated Composite

Abstract

To analyze the deformation process of layered structural elements of inelastic materials, an approach is proposed that makes it easier to solve the problem with complex types of loading. In this method, the package is homogenized, basing 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.
