Structural optimization methods based on the level set method are a new type of structural optimization method where the outlines of target structures can be implicitly represented using the higher order function. But these methods have the problem which does not allow the topological changes increasing the number of holes in the material domain. In this research, we proposed a new topology optimization method based on the level set model and concept of the phase-field theory. In addition, the method is expanded to minimizing the mean compliance problem. Simple example is provided to confirm the usefulness of the proposed structural optimization method.
