“…The honeycomb structure consisting of hollow hexagons is used in many materials, including the core of automobile bumpers, (1) the test barrier for evaluating automobile collision safety, (2) and the inner material of impact buffers at the crossroads of highways. For the honeycomb structure to absorb collision energy efficiently, various structural techniques are adopted such as a multilayer panel in which honeycombs with differently sized hexagons are laminated, (3) and a panel in which the honeycomb wall thickness is continuously varied.…”

In this work, the crushing behavior of a combined honeycomb structure is studied based on the numerical results of finite element method analysis. It is found that the compressive process of the combined honeycomb, which consists of two honeycombs H-1 and H-2 arranged in different directions, can be divided into two steps corresponding to compression of the constituent honeycombs separately. As a result, the compressive load of the combined honeycomb can be predicted from the theoretical results for each honeycomb H-1 and H-2. Also, the scale of the impactor affects the amount of compressive load, and if the radius of the impactor is 7 times larger than the length l of the cell wall, the compressive load reaches the value for the case of impact by a rigid wall.
