Prediction of crushing behaviour of honeycomb structures

A finite element methodology has been developed for predicting the behaviour of honeycomb structures.

Dual-level stress plateaus in honeycombs subjected to

It is demonstrated that honeycombs exhibit dual-level stress plateaus when bucklewaves are initiated and propagate in cell walls, followed by buckling and progressive folding of the cell walls. The abrupt stress drop from peak to crushing plateau in the compressive stress versus strain curve can be explained in a way similar to the quasi-static buckling of a clamped plate.

THE ENERGY ABSORPTION OF ALUMINIUM HONEYCOMB UNDER

Pioneering investigations on the plastic crushing of honeycombs under axial loads were reported from California Institute of Technology by McFarland(1963,1964).
