摘要
本文以勒让德（Ｌｅｇｅｎｄｒｅ）多项式逼近位移场沿板厚度方向的变化规律，考虑了含分层损伤复合材料层合板分层区域的横向剪应力分布，对层合板分层区域的刚度进行了修正，并在此基础上建立了分析含分层损伤复合材料层合板的高阶有限元模型，编制了相应的计算程序，分析了分层损伤对复合材料层合板弯曲变形和应力的影响。
A high order finite element method is developed for analysis of composite laminated plate containing the delamination damage.The Legendre polynomials are introduced into the approximate displacement distributions across the plate thickness,and the laminate stiffness in delamination region can be proposed by changing transverse shear stress distribution.Some examples are given to show the effect of the delamination damage on deformation and stress of composite laminated plate.
