Experimental and numerical study on honeycomb sandwich panels under bending and in-panel compression

Sandwich structures have been extensively employed as lightweight composite components in aerospace and shipbuilding engineering for their high capacity of stiffness, strength and energy absorption. To explore the crushing behaviors of honeycomb sandwiches, both three-point bending (TPB) and in-panel compression (IPC) tests were performed on aluminum honeycomb sandwich panels in this study. The effects of several key structural parameters on...
