Quasi-static Crush Behavior of Aluminum Hexagonal Honeycomb with Perforated Cell Walls

摘要

The crush behavior of aluminum hexagonal honeycombs 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 honeycomb markedly and the strength of honeycomb decreases slightly with the specimen height.
