复合材料层板层间剪切滑移模型

摘要

An accurate model of laminated composite plates with interfacial shear slip is developed. The displacement field, which consists of 3 displacement variables, takes conventional form and results in the simple form of equilibrium equations. The continuity conditions on perfectly bonded interfaces and the conditions of in-plane displacement jump on shear slip interfaces are satisfied by formulating the transverse shear deformation function. So the present model shows very high precision. The solutions to shear slip laminates subjected to different sets of edge boundary conditions are firstly obtained.%针对复合材料层板层间剪切滑移现象,提出了一种精确的分析模型.位移场采用传统形式,位移变量少,平衡方程简洁,但通过构造剪切变形函数,成功地满足了非滑移界面的连续条件和滑移界面的位错条件,使模型具有很高的精度,还首次导出了各类边界条件下滑移模型的解.
