Numerical Aspects on the Computation of Orthotropic Thick Plate

Adriana dos Reis, Éder L. de Albuquerque


Fundamental solutions for bending of orthotropic thick plates are obtained using Hörmander operator and Radon transform. So, they do not have a closed form and numerical integration is necessary to compute fundamental solutions in each field point. In this paper an analysis of the fundamental solution for orthotropic thick plate is presented. Integration aspects are taking into account. It is discussed different approaches in order to carry out the numerical integration in a fast and accurate way. An analysis of computer cost is presented and some results are compared with literature.
