摘要
用基于有限元方法的ANSYS软件和边界元法求解二维弹性静力学问题,推导出二维弹性静力学问题的有限元公式和边界元公式,并采用常单元编写边界元程序。针对两个具体的算例,分别用这两种方法进行求解,并把解得的结果与精确解进行比较和分析,得出一些有意义的结论。
This paper introduces briefly the finite element software ANSYS, and presents the FEM formulation and BEM formulation for 2D elastostatic problems. The elastostatic problem is solved by ANSYS, based on the finite element software and boundary element method respectively. With comparing the numerical solutions with the fundamental solutions, some significant conclusions are drawn.
