As an innovation, concentration diffusion is firstly considered to spread in a wave ways called non-fick diffusion in high temperature. Furthermore, to make concentration diffusion equation satisfy the typical Fick's law in form, inertia chemical potential is proposed. Then the several kinds of variational principles for coupled diffusion and mechanics are established and its corresponding governing equations and boundary conditions are naturally presented from their variational principle, respectively.
