| 摘 要： | 由边界积分方程推导了泊松问题和线弹性力学问题的广义间接边界元法的基本公式。两个算例表明,广义间接法具有常规边界元法的所有优点,并从根本上消除了常规边界元法在处理奇异性和拐点问题上的麻烦,相应地提高了求解精度。

| Abstract: | The fundamental formulas of generalized indirect BEM for the Poisson' s and linear elasticity problems are proposed initiating from the boundary integral equation. Two numerical examples show that the generalized indirect BEM not only possess all the advantages of regular BEM , but also will resolve completely singular problems and corner problems which regular BEM often have to disentangle , and that the precision of numerical calculation can be correspondingly improved . |
