Abstract

Abstract:

As a kind of bionic material, honeycomb structure has remarkable advantages in many fields, such as impact energy absorption, lightweight and so on. Among them, the plateau stress and energy absorption of double-arrow honeycomb (DAH) are higher than that of hexagonal honeycomb under compression load. In order to further improve the specific energy absorption (SEA) of DAH, this paper proposed a circular double-arrow honeycomb (CDAH) by introducing double arc edges to replace the original straight edges of DAH, and the CDAH samples were prepared by 3D printing and quasi-static compression tests were carried. At the same time, the numerical simulation model of CDAH was established based on finite element software, and the accuracy of the model was verified by comparing with the experimental results. The critical impact velocity of CDAH was derived by using the impact wave theory, and the dynamic response of CDAH under different impact velocities in the plane was studied with the verified numerical model. The experimental and simulation results show that, as compared with DAH, both the plateau stress and the energy absorption of CDAH are higher. When the strain reaches 0.6, the SEA of CDAH is 71% higher than that of DAH. And there are obvious inverted “V” and inverted “U” shaped deformation bands under medium and high speed impact, showing good characteristics of negative Poisson's ratio. With the increase of impact speed, the plateau stress and specific energy absorption of CDAH are significantly increased, and the plateau stress under 100 m/s impact is 3 times higher than that under 5 m/s impact, which is helpful to the application in high speed impact protection.

Key words: double-arrow honeycomb, negative Poisson’s ratio, dynamic crushing, specific energy absorption, auxetic material
