Honeycomb structure is used as the shock absorbent to protect precision machines during transport. The purpose of this study is to establish the relation between the energy absorption ability and the honeycomb parameters such as cell size, cell wall thickness and material properties. In this work, as the first step of study, the authors carried out experiments on the collapse of honeycomb structure under quasi-static condition, and clarified the energy absorbing mechanism which is due to progressive buckling. Based on the observed buckling mode, the authors established a finite element model which can represent the debonding failure between the bonded cell walls. The analysis results calculated using this model agreed well with the experimental results for mean collapsing stress and buckling mode.
