【 摘 要 】

The level set topology optimization method solved by reaction diffusion equation not only can avoid the occurrence of numerical problems such as checkerboard, but also can control the structural complexity of the optimization result through adjusting the value of regularization parameter. In this paper, the level set topology optimization method was used to study the multi-material problem, and the topological optimization mathematical model of the multi-material structure was established. Two methods of introduced element stress are studied. The typical example solved by this model has realized the reasonable layout of multi-material.
