crushing analysis of metal honeycombs

QuasiStatic Crush Behavior of Aluminum Hexagonal

The crush behavior of aluminum hexagonal honeycomb with perforated cell walls under outofplane quasistatic 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 densifiion state.
