摘要	In this paper, we shall discuss kinetic equations of composite materials and their interfaces, which is a typical multiphysical problem, date to the existence of very thin interfaces. A multiphysical model and a transscale computational method will be presented. Our method is composed of four parts: the first one is the first-principle calculation (e.g., TB-DFT method) for calculating the total energy and the elastic constants of interfaces; the second one is the homogenization method for evaluating the effective elastic constants of macroscopic structures of composite materials; the third one is the multiscale method for computing the stress field of macroscopic structures; and the final one is the quantum molecular dynamical method (e.g.,TBMD) for calculating the local stress field of the interfaces. Some numerical results are reported. The rigorous proofs of some main theoretical results will be given in the Appendixes.
