摘要
Abstract
A structural shape optimization algorithm based on the evolutionary structural optimization ( ESO) method in conjunction with element error estimate and adaptive FEM is presented. B-splines are used to describe the boundary of the design domain; the shape of these B-splines is governed by a set of master nodes which can be taken as the design variables. The optimal shape of the design boundary with constant stress is a-chieved iteratively by the movement and update of the position of the master nodes based on nodal stress leveling. The result quality, in terms of accuracy and efficiency, is tested and discussed with an analytical solution.关键词
