In-plane dynamic crushing of honeycombs—a finite element study

The in-plane dynamic behaviour of hexagonal aluminium honeycombs has been studied in this paper by means of finite element simulation using ABAQUS. The influences of honeycomb cell wall thickness and impact velocity on the mode of localised deformation and the plateau stress are investigated. Deformation modes in the X1 direction change significantly with different values of cell wall thickness and impact velocity. Three deformation modes are...
