| 中文摘要: |
| 首先改进文[1]的互补变分原理。再建议一种较为普遍性的方法,导出精确的边界积分方程。最后给出变分有限元及边界元解,算例证实有限元格式及迭代方式有效。 |
| 英文摘要: |
| We first improve the complementary variational principle given in ref. [1],and again suggest a general method for deriving the exact nonlinear boundary integral equation. Finally we obtain the hybrid and boundary element solution and are verified by the numerical results. |
