A varying cell-size distribution method is introduced to construct 2D and 3D graded cellular structures. Deformation feature and stress history of 2D graded cellular structures under mass impact are obtained from the cell-based finite element models and they are compared well with the predictions of the shock model. The design of the relative density distribution of graded cellular structures is preformed with the shock model considering the deceleration of the striker as a constant and verified by a 3D graded cellular model. It is illustrated that the shock model could be used to guide the crashworthiness design of graded cellular structures.
