摘要：

In this paper, the energy absorption of single-wall corrugated fibreboard with a trapezoidal core under edgewise crushing load was studied experimentally and analytically, and a physical surface bonding was assumed to represent the interaction between the fluted board and the linerboard based on the production process of corrugated fibreboards. A new folding element was proposed, including two boards and two trapezoidal corrugated cores with central symmetry. Moreover, three folding modes of the fluted board were proposed based on experimental phenomena, and a plateau stress model was characterized by the geometry parameters of the corrugated fibreboard. It was found that the plateau stress predicted by the developed model compared well with the experimental results, from which one can conclude that the proposed model was effective and helpful for corrugated structures design and parameters selection to meet different strength requirements.
