Abstract
In this paper, the crushing behavior of hexagonal honeycomb structure with finite width subjected to in-plane compressive loading is studied by using finite element method. It is found that stress-strain curves are classified roughly into two types. They are influenced by ratio of thickness of cell wall, ratio of the work hardening, and state of defects. In addition, for a honeycomb structure in which defects assembles in a row, the peak stress can be predicted by using a model without defect. For a model with defect, the energy absorption characteristic doesn't fall off very much.
