ALUMINIUM HONEYCOMB UNDER QUASI-STATIC COMPRESSIVE LOADING: AN EXPERIMENTAL INVESTIGATION

The effect of the aluminium honeycomb with the crushing load-displacement characteristics and the mode of deformation under quasi-loading were investigated. The experimental results for aluminium honeycomb under quasi-static condition applied in 3 principal directions are reported. The specimens under lateral loading showed three zones: Zone 1 is the initial elastic state, and then followed by the plateau region in zone 2. Zone 3 shows a monotonically stiffening region, associated with densification of the material. However, under axial compression, initial collapse occurs at a peak load, and is then followed by the amplitudes of little peaks, which signify progressive folding collapse. The collapse load due to lateral loading is compared with mean load in axial compression loading.
