Abstract

A move limit strategy is proposed for level set based structural optimization, which offers a tool to restrict the allowable change of the free boundary of a structure in each iterative step of optimization. To realize the move limit strategy, a function for modifying the extended design velocity is proposed. Application of the move limit strategy is demonstrated by several numerical examples of 2D structures. The results show that the move limit strategy is helpful to improve the stability and convergence rate of level set based structural optimization.
