Axial Symmetric Elastic Analysis with Gravity Load in Non-Homogeneous Materials by Triple-Reciprocity Boundary Element Method

Abstract

In general, internal cells are required to solve elastic problems with gravity load in non-homogeneous materials using a conventional boundary element method (BEM). However, in this case, the merit of BEM, which is ease of data preparation, is lost. In this study, it is shown that axial symmetric elastic problems with gravity load in non-homogeneous materials can be solved without the use of internal cells, using the triple-reciprocity BEM. A body force distribution is interpolated using boundary integral equations. A new computer program was developed and applied to solving several problems.
