摘要

A critical aspect in all implementations of the boundary element method is an accurate computation of the kernels' integration. The These kernels are singular or hypersingular when the collocation point belongs to the integration element, and different techniques have been devised to tackle this problem. Another important issue is the integration of the kernels when the collocation point is close to but not in the integration element.
