Crushing Behavior of Combined Honeycomb Structure

Abstract

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.
