The paper concentrates on the numerical evaluation of nearly singular kernel integrals commonly encountered in boundary element analysis. Limitations of the method developed recently by Huang and Cruse (1993) for the direct evaluation of nearly singular kernel integrals are analysed and pointed out.

## Abstract When applied on the basis of the exact cylindrical wire kernel, thin‐wire moment‐method formulations yield singular integrals, the direct numerical calculation of which possesses certain difficulties. The scope of this work is the assessment of a simple singularity isolation technique f

The paper attempts to improve the efficiency of a general method developed previously for computing nearly singular kernel integrals. Three new formulations are presented by following an approach similar to that used in the previous method. Their numerical efficiency is compared with the previous me
