| Abstract: | Internal forces of elastic structures are calculated by using three-node quadratic boundary element method in which displacement and traction at elastic structures' boundary are more accurately depicted.The displacements and internal forces of structures on internal points are obtained.The example in this paper proves the accuracy of the method. |
