Abstract

Spline boundary element analysis of plane orthotropic elastic layer L.Z. Jiang, J.S. Lee Department of Civil and Environmental Engineering, Clarkson University, Potsdam, ABSTRACT A solution method for stress analysis of a plane orthotropic layer is presented in this paper. Based on the state space approach and the Fourier transform, the fundamental solution for an orthotropic elastic layer under the action of arbitrary surface loads and volume forces is obtained in the form of infinite integrals, which are then evaluated numerically. In order to remedy the slow convergence of the numerical integrals associated with the fundamental solution, a procrustean technique is proposed. The fundamental solution is then implemented in the spline boundary element method. As an illustrative example, a problem of an orthotropic layer containing an elliptic cavity is considered and numerical results are compared to the finite element solutions.
