The Characteristics Of Load Versus Displacement Of Paper Honeycomb : An Experimental Investigation

The influence of paper honeycomb core on the energy absorption capability was studied. Simple mechanism for compression test was constructed. Maximum stress and deformation of each specimen were compared with the results from analyses of static compression stress-strain curves. The specimen under axial loading showed three zones. Zone 1 is the initial elastic state and the followed by the plateau region in zone 2. Zone 3 shows a monotonically stiffening region, associated with densification of the material. The locking strain is defined by intersection of two lines and the locking strain in experimental is 9 mm. Therefore, the value of locking strain each paper honeycomb stress-strain curves are used to define area under the curve to obtain energy absorption and mean load. The theoretical mean load used in metal honeycomb is adapted and compared with experimental results
