Abstract

An extension of the boundary element method in orthotropic materials for multiply connected regions N. Kadioglou and S. Ataoglu Department of Civil Engineering Technical University of Istanbul, Turkey Abstract An improvement is introduced to solve the plane problems of linear elasticity by Boundary Element Method for orthotropic materials. It is considered that the problem to be solved is the first fundamental problem and the region concerning the problem is multiply connected. The kernels of the standard formulation are the functions of two com- plex variables depending on the coordinates and the material con- stants of the orthotropic medium. Boundary of the region is idealized as a collection of line segments.The end points of these segments are nodal points. N is the number of the nodal points. 2N integral equa- tions can be written by assuming there is an singular loading at every nodal point on each direction. In these integral equations, the inte- grals over the boundary are r
