| Abstract: | Superposition of nodes is put to use for the analysis of three dimensional elastic mechanics angle problem.A method is introduced to deal with boundary integral equation of 3D-BEM.Isoparametric conver- sion and interpolation approach is used in this process.Nodes on the angle location take on discontinuity su- perficial force,which result in solution is difficult.With this method,it is solved.This method is provided with a great deal of merits such as simple operation,convenient calculation and accurate result.It is predomi- nant especially in such situation that stress convergence appears on angle position. |
