Abstract

In this paper a mathematical model based on a multi-scale asymptotic technique for the dynamic description of honeycomb structures is presented. The technique is used to evaluate an equivalent orthotropic model of the honeycomb. The derivation is based on an asymptotic analysis for periodic structures developed by Bensoussan, Lions and Papanicolaou. The method is totally general; in fact, it is applied to Cauchy’s partial differential equations that describes the dynamics of an elastic material. Elastic and density characteristics are determined in terms of the cell geometry and material of the honeycomb. A numerical validation is carried out by using a finite-element modeling (FEM) numerical simulation.
