Honeycomb Elastic Material Properties: A Review of someExisting Theories and a New Dynamic Approach

摘要

The influence of the nine orthotropic material properties of honeycomb on the dynamic response of a finiternelement model of a simple supported sandwich plate are examined. Fifteen available theories from thernliterature for the material properties of honeycomb are reviewed and their values calculated for a HexWebrn5.2-1/4-25(3003) Aluminium core. The agreement between the theoretical material properties and the majorrnASTM(American Society for Testing and Materials) standard test methods is investigated. A new and simplerntechnique is described for measuring the dynamic shear moduli of honeycomb materials and its values arerncompared with those presented in the literature.
