The structure transition from compression state to dilation state in both heavy-particle sections gives rise to the crossover of the energy decay in one-dimensional composite granular chain. And the structure transition closely relates to the change in state of motion of heavy grain at both interfaces. The analysis demonstrates that the change in state of motion gives rise to the great difference of reflectivity in both branches, which induces different rates of energy decay of light-particle section in both branches.
