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.

为了分析非弹性材料层状结构元件的变形过程，提出了一种更容易解决复杂载荷类型问题的方法。在该方法中，包被均质化，基于其替换为沿厚度具有均质结构的板，其力学特性通过基于简单加载类型的数值实验结果的识别方法确定。提出了解决具有线弹性外层和粘弹性中间层的三层板的循环张力公式化问题的结果，这些结果是通过标准方法和建议方法获得的。
