Isotropicalized Boundary Element Analysis for Torsion Problems of Orthotropic Bar

In this paper the simple boundary element method for solving the simple torsion problem of orthotropic bar is proposed. The simple torsion problem of orthotropic bar is changed into a torsion problem of isotropic bar by coordinating conversion method. The simple fundamental solution of the torsion problem of isotropic bar is utilized for boundary element analysis. The numerical results show that this method is valid for the solution of torsion problems of orthotropic bar.
