| 摘 要： | 本文根据广义协调条件,构造了一个广义协调板膜耦合三角形壳元,然后利用分层子单元技术,将其从线弹性领域推广到弹塑性领域.导出了薄壳广义有限元的一般列式.最后采用文提出的数值方案进行求解,并编制了程序 EPATS.算例表明:单元收敛性态很好,有较高的计算精度.

| Abstract: | In this paper,the generalized conforming triangular shell element is proposed based on generalized conforming conditions.And it is generalized form linear elastic field to elas- tic-plastic field applying to the technique of layered sub-elements.The nonlinear algebraic equations is solved applying to numerical methods proposed reference.According to the project above,program EPATS is developed.The behaviour of the element is shown good by the numerical examples in the paper. |
