Abstract

Level set-based shape optimization methods are proposed as new type of structural optimization method and we proposed a new topology optimization method based on the level set method and concept of the phase field method. This paper proposes a level set-based topology optimization method with an uniform cross-section surface constraint based on our proposed level set-based topology optimization method. First, basic details of the level set-based topology optimization method are briefly discussed. Next, based on the regularization method, the topology optimization method considering a uniform cross-section surface constraint is formulated. Finally, three-dimensional example is provided to confirm the validity and utility of the proposed topology optimization method.
