Abstract

A refined calculation method is proposed for a three-layer (sandwich) structure in the edge-effect zones, taking account of how motion of the load-bearing (external) layers affects the stress–strain state. Functions approximating the stress distribution in the central layer (filler) are used to determine the stress–strain state of the three-layer structure. Those functions should correspond to the actual behavior of three-layer structures.

三层结构中的层运动对其应力-应变状态的影响

摘要

考虑到承重（外部）层的运动如何影响应力-应变状态，对边缘效应区域中的三层（三明治）结构提出了一种改进的计算方法。逼近中心层（填料）中应力分布的函数用于确定三层结构的应力-应变状态。这些功能应与三层结构的实际行为相对应。
