摘要：
Topology optimization has become a very popular field during the last decade, tempting thousands of scholars to dive into this discipline with a diversity of tools, among which level set based method is the celebrated one. But conventional level set based method for topology optimization has the flaw that it is difficult to nucleate holes. In this paper, we incorporate topological sensitivity to help holes creation process. In order to achieve higher order accuracy, trapezoidal method is utilized. Sensitivity filter is also employed to make result a better structure. The effectiveness of the method we propose is manifested in numerical examples at last.
