This paper describes two strategies for the accurate computations of polential derivalives in boundary element methods. The first method regularizes the quasi singularity in a fundamental solution by referring the potential and its derivatives at the boundary point nearest to a calculation point in
The boundary node method (BNM) is developed in this paper for solving potential problems in three dimensions. The BNM represents a coupling between boundary integral equations (BIE) and moving least-squares (MLS) interpolants. The main idea here is to retain the dimensionality advantage of the forme
In the paper, an ~vestigation into the stress intensity factors of mixed-mode three dimensional crack problem is studied. In the method presented in the paper, the number of elements and nodes can be decreased greatly while computational accuracy and efficiency increase, the continuous functions of
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-
