The evaluation of the inverse distance singular integrand which occurs in the three-dimensional boundary element formulation of potential problems is treated using weighted Gaussian integration. Three methods are investigated. The first involves repeated use of a one-dimensional Gaussian formula in

Interpolation to boundary data and one-dimensional Overhauser parabola blending methods are used to derive Overhauser triangular elements. The elements are C'-continuous at inter-element nodes and no functional derivatives are required as nodal parameters. These efficient parametric representation e
## ABSTRA CT A numerical scheme for solving the three dimensional interior acoustic problem governed by the Helmholtz equation has been developed. The main feature of this formulation is that the singularity can be removed analytically. The boundary integral equation is solved for a specific geome
In the paper, a new kind of stress singular element is introduced for crack problems. This kind of element is more simple and widely used than those presented before. In the paper, a cube with embedded circular crack and a first kind Benchmark problem are studied. The study shows that using quarter-
