A Kind of Fast Multipole-BEM Applied in 3-D Elastic Contact Problem

摘要

In this paper, by use of Talyor series expansion, the boundary integral equation about 3-D elastic contact problem is discrete. In boundary, basic solutions contain singularity term 1/r, which influence the application of multipole expansion method, but by Laplace transformation, reduced to exponential series. Then this method improves the original FMM and provides theory analysis for applying FMM in engineer.
