01/01/1983  Crushing analysis of metal honeycombs 167 We shall proceed now to the evaluation of energy dissipated in the dis- continuous deformation fields. The general expression for the rate of energy dissipation is E2 = ;L M0$d (4.7) where 0 is the rate of rotation at the plastic hinge, L is the length of the hinge lines and M0 = I/4 o0 h2 is the fully plastic bending moment. The length of each

Crushing analysis of metal honeycombs - ScienceDirect

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 first developed for an ...

This analytical model predicts the mean crushing stress of the metal square honeycomb as a function of both the geometrical parameters and its material, while the predicted wavelength of the folding mode is just a function of the geometrical parameters. Finally, the experimental tests have been performed to verify the preciseness of this theoretical model.
