Models for the elastic deformation of honeycombs
I.G. Masters,Kenneth E. Evans +1 more
TL;DR: In this paper, a theoretical model was developed for predicting the elastic constants of honeycombs based on the deformation of the honeycomb cells by flexure, stretching and hinging, which can be used to derive expressions for the tensile moduli, shear moduli and Poisson's ratios.

Biaxial crushing of honeycombs: - Part 1: Experiments
S. D. Papka,Stelios Kyriakides +1 more
TL;DR: In this article, the same honeycomb is crushed biaxially in a custom testing facility between rigid platens which can be moved independently in two orthogonal directions, and the results showed that the highest energy is required when the specimen is crushed at the same rates in the same directions.
