Abstract
Honeycomb structures are light weight cellular structures having high strength to weight ratio with enormous applications in aerospace industry, high speed automobiles, computers and other electronics equipment bodies and recently as flexible structures and mechanisms. In this paper a review of mathematical models for stress strain behaviour of two dimensional honeycomb structures is presented. As proposed by different authors, expressions for in-plane Elastic Moduli and shear Modulus are presented and compared on same scale dimensions. In addition to that, effects of number of unit cells on effective in plane and out of plane Moduli of the testing specimen for regular honeycombs and open and closed cell foams, are also reviewed.
Highlights
Honeycomb cellular materials are widely used in light weight construction especially in aircrafts, missiles, space vehicles, compliant mechanisms and flexible structures and high speed automobiles
Using cell wall bending model which is called Cellular Material Theory (CMT), Gibson and Michael (1988) determined the in plane Moduli by considering cell walls as flexures that are fixed at one end and guided at other end as considered by Abd ElSayed et al (1979)
In early years honeycomb structures were used as sandwich panels, using their property of “high out of plane strength to weight ratio” as compared to constitute materials
Summary
Honeycomb cellular materials are widely used in light weight construction especially in aircrafts, missiles, space vehicles, compliant mechanisms and flexible structures and high speed automobiles.
