Abstract
The paper deals with numerical integration of weakly singular integral s arising in 2D BEM. In all, three fundamental solutions are addressed : steady state conduction in moving bodies, axisymmetric potential and axisymmetric elasticity. It is shown how these fundamental solutions can be rearranged to a form suitable for logarithmically weighted Gaus sian integration. An algorithm of evaluating weakly singular integrals for arbitrary location of the singular point is described. (C) 1997 E lsevier Science Ltd.
