Abstract: Taking proposed proposition about the grid-based simulation for the unit cell of composite material with periodicity into account, and choosing position of voids as optimal variables, this paper builds an optimal model for the two-phase material with maximizing the effective thermal conductivity of the material. Then the paper seeks its solution by using the genetic algorithm. The numerical results show that the optimal model is reasonable and the optimal algorithm is also effective. Furthermore, several optimal unit cells are obtained.
