| 摘 要： | 基于板的一阶剪切理论和Zig-Zag变形模型，采用有限元分析方法，研究了在热-机械力耦合作用下，含损伤复合材料夹层板的线性和非线性屈曲问题，在分析中考虑了材料热和机械性质随温度变化的特征以及表板与芯体间的界面桥联影响，并通过对典型算例的分析和讨论，说明了桥联刚度和热-机械力耦合效应对含损伤复合材料夹层板结构的屈曲性态的影响是十分显著的。

| Abstract: | On the basis of the first order shear deformation plate theory and Zig-Zag deformation model, a linear and/or nonlinear buckling analysis for the damaged composite sandwich plates under thermal-mechanical combining loading is carried out by using finite element method. The temperature dependent thermal and mechanical properties of the materials and interfacial bridging effect between the faces and core are also considered. Numerical results and discussions from some typical examples show that the influences of thermal-mechanical coupling and bridging stiffness upon buckling behavior for the damaged composite sandwich plates are significant. |
