摘要
讨论一种通用有效的平板壳元用于板壳问题的弹塑性分析，单元中每个结点有六个自由度，此种单元由基于Ｍｉｎｄｌｉｎ板理论的平板弯曲单元与带有平面内转动自由度的平面膜单元组成．沿单元厚度方向采用分层方法进行弹塑性分析，算例结果表明本文方法合理、可行．
A general and efficient element is discussed for elasto plastic analysis of plates and shells. This element has six degrees of freedom per node, and is obtained by combining the Mindlin plate bending element and the membrance element with driling degree of freedom. The layered model is used for elasto plastic analysis in the thickness direction. The results of numerical examples show that the present method is feasiable and reliable.
