对于较厚的层合板,基于一般高阶理论的应力计算结果往往不能满足工程要求.用基于高阶理论的P型有限元法分析层合板的应力分布规律.位移场用Legendre多项式的积分进行插值,用维数缩减法把三维的层合板问题化成二维问题,用静力凝聚把单元内部自由度凝聚掉,这样可有效地计算各向异性材料层合板的应力分布.结果表明,采用P型有限元求解任意厚度、任意方向铺设的四边形复合材料层合板问题是可靠的.

For thicker laminates, the stress calculation results based on general higher-order theory often cannot meet the engineering requirements. The stress distribution law of laminate was analyzed by the P-type finite element method based on high-order theory. The displacement field is interpolated by the integral of the Legendre polynomial, the three-dimensional laminate problem is reduced into a two-dimensional problem by dimension reduction method, and the internal degrees of freedom of the element are condensed by static condensation, which can effectively calculate the stress distribution of the anisotropic material laminate. The results show that P-type finite elements are used to solve the problem of quadrilateral composite laminates laid in any thickness and direction.
