Boundary Element Analysis of Three-Dimensional Contact Problems by the Method Called Dynamic Mesh

Abstract

Three-dimensional elastic contact problems are analyzed by the boundary element method. The boundary line of the contact area is calculated accurately by the method called "dynamic mesh". For such calculation, linear triangular elements are used. These elements are integrated analytically to estimate the singular integrals accurately. Inner stresses of contact bodies are calculated by numerical differentiation of displacements. The conclusion of this report is compared with the results of other methods which have already been reported in public. The effectiveness of "dynamic mesh" is certified by practical examples.
