| Abstract: | A useful and accurate new algorithm suitable for the determination of boundary variables of the lioear element in the plane elasticity problem is presented. Based on the difference between the boundary variables determined by the algorithm presented and the correspondingly given boundary values, an bjective measurement of the accuracy ia BEM is suggested. This objective measurement can be used to estimate the error of a BEM solution when the problem is too complicated to be solved analytically and no analytical solution is available for comparison. Several numerical examples are given. |
