摘要
本文针对文献［１］所述复合材料层合板三维模型，在三维线性弹性理论基本方程和经典变分原理的基础上，通过分块矩阵运算和线性Ｌａｇｒａｎｇｅ乘子法，推导出比文献［１］更全面更系统的基本方程和变分原理，使复合材料层合板三维线性理论臻于完整。
In ref [1],a model of 3-D composite laminate theory was described. In the present paper,based on the basic equations about 3-D linear elasticity and class- ical varlational principles.by the block matrix operation and the Lagrange's method of multipiers, a series of basic equations and variational principles are obtained,which are more complete and more systematic than that in ref[1].
