摘要
在这个工作，把问题弄弯的 elasto 塑料的板的有限元素分析用转变被执行矩形的板元素。转变板元素的形状功能基于一条实际规则被导出。转变板元素都是四边的并且能被用来用元素的最小的数字获得有效有限元素模型。包括转变元素的模型的网孔集中率与常规元素模型相比。验证发达元素，简单测试被表明，各种各样的 elasto 塑料的问题被解决。他们的结果与 ANSYS 结果相比。
In this work, the finite element analysis of the elasto-plastic plate bending problems is carried out using transition rectangular plate elements. The shape functions of the transition plate elements are derived based on a practical rule. The transition plate elements are all quadrilateral and can be used to obtain efficient finite element models using minimum number of elements. The mesh convergence rates of the models including the transition elements are compared with the regular element models. To verify the developed elements, simple tests are demonstrated and various elasto-plastic problems are solved. Their results are compared with ANSYS results.
