Shape design sensitivity analysis of 2D anisotropic structures using the boundary element method

Research output: Contribution to journal › Article › peer-review

Abstract

A directly differentiated form of boundary integral equation with respect to geometric design variables is used to calculate shape design sensitivities for anisotropic materials. An optimum shape design algorithm in two dimensions is developed by the coupling of an optimising technique and a boundary element stress analyser for stress minimisation of anisotropic structures. Applications of this general-purpose program to the optimum shape design of bars and holes in plates with anisotropic material properties are presented. © 2002 Elsevier Science Ltd.
