Crushing behavior of honeycomb structure: a review

Abstract

This article concludes some of the important observation regarding quasi-static and dynamic crushing response of honeycomb structure carried out by authors and addressed in the literature. The behaviour of honeycomb structure has been reported through experimentation, mathematical and numerical models. The influence of cell wall thickness, node length, cell size and loading has been studied in detail leading to some important findings which have not been addressed earlier. The crushing responses of honeycomb structure have been studied in both out-of-plane and in-plane loading condition. Moreover, its bending behaviour has also been reported in few studies. Geometrical core configuration and geometric property like cell size, cell wall thickness and node length etc. play a defining role in administrating potential of honeycomb. Relative density was a vital property of honeycomb dependent on cell configuration and geometric properties. Facesheet material and thickness majorly effects the energy absorption capability of the core during dynamic projectile and impulsive impacts.
