Abstract
Abstract The early studies on mechanical model of paper honeycomb structures were always concentrated on static situation, however, paper honeycomb would meet some random events of impacting and vibration during the process of transportation. Considering the virtual working circumstance, dynamic experiments under medium and low strain rates were undertaken and corresponding models of mechanical properties were derived. There exists a certain strain-rate effect which leads to the difference of mechanical properties between dynamic and static condition. A mechanical model was given to estimate plateau stress and yield stress at different strain rates based on experimental data by employing the methods of Cowper–Symonds model and piecewise function. The conclusion can be applied to characterise and improve the compressive properties of paper honeycomb structure efficiency.
