摘要

对无单元伽辽金法(EFGM)和边界节点法(BNM)进行了改进。在用隐式函数表示边界后，使用该函数对矩阵元素进行评估。计算结果表明，该方法的精度甚至高于双互易边界元法。

Development of two-dimensional meshless approaches without using integration cells

The Element-Free Galerkin Method (EFGM) and the Boundary-Node Method (BNM) have been reformulated without integration cells. After a boundary is represented in terms of an implicit function, matrix elements are evaluated by use of the function. The results of computations show that the accuracy of the reformulated BNM is even higher than that of the dual-reciprocal boundary-element method.
