Abstract A method for determining the crushing strength of hexagonal cell structures subjected to axial loading is given. The method is based on energy considerations in conjunction with a minimum principle in plasticity. The problem is shown to be equivalent to the analysis of a system of collapsing angle elements undergoing bending and extensional deformations. The theory is Axial crush of metallic honeycombs ScienceDirect,01/05/1997· Quasi-static test In the quasi-static tests on the honeycombs, the specimens were back-supported on a thick, fiat plate.
