Stress analysis with centrifugal load in non-homogeneous materials by triple-reciprocity boundary element method

摘要

In general, internal cells are required to solve elastic problems with a centrifugal load in non-homogeneous materials using a conventional boundary element method (BEM). However, in this case, the merit of the BEM, which is the ease of data preparation, is lost. In this study, it is shown that two-dimensional elastic problems with centrifugal load in non-homogeneous materials with variable mass density 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 is developed and applied to solve several problems.
