| Abstract: |
| Taking the B-flute and C-flute corrugated paperboard as research objects, the corrugated paperboards were conducted quasi-static compressive tests under 7 different compressing rates to examine deformation modes and static properties. Transverse compression mechanical characteristics and energy absorption properties were analyzed, energy absorption diagrams, energy absorption efficiency curves and specific energy absorption (SEA) curves were drawn. The results showed that, there was neglected effect of low strain rates on optimum stress of energy absorption, energy absorption efficiency and specific energy absorption of corrugated paperboard, while section geometry of the panel affected the energy absorption properties of corrugated paperboards more obviously. At the same compression rate, energy absorbed per unit volume, structural deformation utilization rate and specific energy absorption of B-flute corrugated paperboard were all greater than that of C-flute panel. |
