Numerical Modeling of Elastic Modulus and Bucking Load of Honeycombs
Abstract:
In this paper, both equivalent Young’s modulus and bucking load of the honeycombs are calculated using the finite element method. Honeycombs consisting of either regular hexagonal, equilateral triangular or square cells are considered. Numerical results are systematically compared with theoretical results from other literature. It is found that honeycombs display orthotropic properties. Such a fact is different from that reported in open literature. Moreover, the buckling modes are discussed, and the modified expressions of the equivalent modulus and bucking load are given.
