| 摘 要： | 对层合板引入小应变中转动几何非线性假设，位移模式考虑了横向剪切应力及其连续性，有采用罚单元的方式构造了简单，协调的八节点等参单元，并应用于层合板的应力分析，取得了很好的数值结果。

| Abstract: | The geometrical nonlinear of moderately rotation is introduced in the analysis of laminated plates, the transvers shear tress and its continuity were considered at the same time.With the help of penalty element, a simple and harmonious 8-node isoparametric element was proposed and applied in the stress analysis. The numeric results are very good. |
