摘　　要：对于非线性复合材料层合板壳的有限元分析,关键在于如何根据结构分析的特点构造其数学模型。按一次板壳理论,以四边形四节点单元为例,介绍了其数学建模的过程与方法,导出了层合板壳有限元分析模型,并给出了基于软件工程的计算机逻辑模型。The key to the nonlinear finite element analysis of composite laminated plates and shells lies in the construction of its mathematical model according to the characteristic of engineering structural analysis.Based on the first approximation shell theory,the process and method of mathematics modeling for a four-node quadrilateral shell element is described in detail.The finite element analysis model of laminated plates and shells is derived,and the computer model based on software engineering is presented.
