  • The theoretical mode of velocity attenuation of rigid mass and the stress wave propagation in layered cellular materials under dynamic impact loading has been proposed based on the 1-D wave theory and the dynamic response process of a foam rod strike by a rigid mass has been studied. A finite element (FE) validation has been conducted by employing ANSYS/LS-DYNA software, agreeing well with the theoretical results. The compared results show that the triple layered graded foam material has better impact reduction and energy absorption capacity than the uniform foam with the same mass. Due to the reflected wave and the strain hardening effects not considered in the theoretical model, there are some acceptable errors between the theoretical and FE results.
