In this paper, the in-plane impact characteristics of functionally graded honeycombs are studied with the consideration of defects. The influences of the defect location on the dynamic crushing characteristics of the honeycombs are discussed. Based on a given relative density, the dynamic deformation modes and energy absorption of the honeycombs with different density gradients are investigated. The results show that the energy absorption abilities for the honeycombs with the negative density gradient are much stronger than those with the positive ones. This paper is helpful for the design and analysis of the mechanical characteristics of the honeycomb materials and structures.
