Abstract—

The stress-strain state of a thin adhesion layer in a layered composite is investigated under shear loading taking into account its possible elastoplastic deformation. The layer thickness is treated as a linear parameter. Analyzed is the analytical solution obtained on the basis of a simplified formulation of the problem in differential form. For small layer thicknesses, a generalized criterion for the transition to the state of plasticity associated with a linear parameter is proposed.

薄胶层的剪切弹塑性变形模型

摘要-

考虑到其可能的弹塑性变形，在剪切载荷下研究了层状复合材料中薄粘附层的应力-应变状态。层厚度被视为线性参数。分析的是基于简化形式的问题的差分形式获得的分析解决方案。对于较小的层厚度，提出了与线性参数相关的过渡到可塑性状态的通用准则。
