摘要
首先改进互补变分原理。再建议一种较为普遍性的方法,导出非线性边界积分方程。最后给出变分有限元及边界元解,算例证实有限元格式有效。
We first improve the complementary variational principle. Again a general method for deriving the nonlinear boundary integral equation is suggested. Finally,we obtain the variational finite element , and the boundary clement solution, and the numerical results have varified that the element formulae are effective.
