Papers by Keyword: Hexagonal Honeycomb

Abstract: The crush behavior of aluminum hexagonal honeycomb with perforated cell walls under out-of-plane quasi-static loadings was experimentally investigated. The honeycomb specimens with different heights were compressed in axial direction under displacement control. There are four sequential deformation stages during compression: linear elasticity, buckling, crushing and densification state. The performances of hexagonal honeycombs with perforated cell walls were compared with those of imperforated hexagonal honeycombs with the same sizes. The results show that the perforated holes weaken the strength of honeycombs markedly and the strength of honeycomb decreases with the specimen height.

Abstract: According to the related experimental standards, the finite element (FE) methodology to calculate the in-plane and out-of-plane moduli of hexagonal honeycombs (HHs) is designed by simulating the experimental loadings. Some simulations were carried out for the hexagonal honeycombs with different configuration parameters. The FE results are consistent with the theoretical ones, which verifies the reliability of FE methodology.
