A performance-based optimization method for topology design of continuum structures with mean compliance constraints

摘要

A performance-based optimization (PBO) method for optimal topology design of linear elastic continuum structures with mean compliance constraint is presented in this paper. The performance-based design concept is incorporated in continuum topology optimization, which is treated as the problem of improving the performance of a continuum design domain in terms of the efficiency of material usage and overall stiffness. A simple scheme is employed in the proposed method to suppress the formation of checkerboard patterns.
