摘要
本文简述了求解结构稳定性问题的有限元理论基础。用张量的形式指导了一般层合板矩形单元的节点力和节点位移关系方程,祥细推导了一般层合板四节点矩形单元的几何刚度矩阵的公式及其显式。
The complete derivation of the geometrical stiffness matrix of 4 - node rectangular element adapted for multilayered plates and the corresponding explicit expressions are given as well as the FEM basic theory solving structural stability and the relationship between node -force and node-displacement in the form of tensor being presented in this paper.
