胶合搭接接头*
Analysis of Adhesive Lap Joint

摘要: 本文以能量法求解无胶层厚度的搭接接头的层间应力.接头是由两相同的狭长板条组成.讨论了两种情形:一是各向同性材料的,一是正交各向异性材料的.由于构成接头的材料不同,层间应力的分布长度与数值均有很大差异.Abstract: This paper is to solve the interlaminar stresses of adhesive lap joint by the energy method without considering the adhesive layer. The joint is made of two identical narrow plates. Two cases are discussed: one is for the isotropic material and the other is for orthotropic material. Because of the different materials forming the joint, the length of distribution and the magnitude of the interlaminar stresses for the two cases will be very different.
