A Sigmoidal and Distance Combined Transformation Method for Nearly Singular Integral on Asymmetric Patch

A Sigmoidal and Distance Combined Transformation Method for Nearly Singular Integral on Asymmetric Patch

This paper is devoted to developing a new computational method for nearly singular integral computation in the application of the boundary element method for the analysis of thin-shell-like structures in mechanical engineering. Based on the traditional distance transformation method, a sigmoidal tra...
