ALUMINIUM HONEYCOMB UNDER QUASI-STATIC COMPRESSIVE LOADING: AN EXPERIMENTAL INVESTIGATION
Keywords:
Aluminium, honeycomb, quasi-static compressive loadingAbstract
The effect of the aluminium honeycomb with the crushing load-displacement characteristics and themode of deformation under quasi-loading were investigated. The experimental results for aluminiumhoneycomb under quasi-static condition applied in 3 principal directions are reported. The specimensunder lateral loading showed three zones: Zone 1 is the initial elastic state, and then followedby the plateau region in zone 2. Zone 3 shows a monotonically stiffening region, associated withdensification 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.
