Paper Abstract

Dynamical deformation and collapse process and stress wave mechanism of aluminum honeycombs subjected to the in-plane impact of a rigid impactor were investigated experimentally. Deformation process was visualized using a high-speed video camera and reaction forces were measured using force-gauges at the contact surface between the honeycomb and fixed wall. Also, numerical simulation was made using a shock code. AUTODYN-2D. Since an aluminum honey-comb has an anisotropic nature owing to its cell shape and cell arrangement, the direction of impact greatly affects the deformation characteristics. The present results were compared with our previous results for different impact direction.
