摘要
采用三维退化等参中厚壳元和分层模型，建立了分析弹塑性和几何非线性各向异性板壳的有限单元法．为克服退化壳元出现剪切和薄膜自销问题，采用９节点Ｈｅｔｅｒｏｓｉｓ单元并采用选择积分方法．文末算例表明所编程序的可靠性和通用性．
The elasto-plastic and geometrical nonlinear anisotropic plates and shells are analysed using three dimensional degenerate shell element and layered model. The shear and membrance locking phenomenon can be effectively overcome using 9-node Heterosis element and selected integration. Examples presented show the applicability and versatility of the given program.
