Analysis of Honeycomb Structure

Abstract

The Honey Comb Sandwich construction is one of the most valued structural engineering innovations developed in the composite industry. It finds its applications in industries like aerospace, aero plane, transportation, rails etc. The behaviour of honeycombs subjected to three point bending is investigated using Hypermesh and LS-DYNA. The finite element (FE) results like deflection and critical load are verified by theoretical calculation. The honey comb sandwich CAD model is prepared in CATIA software. The core material used in the analysis is copper, steel, aluminium and titanium and the steel material is used for faceplates. The analysis is carried out by varying the thickness of faceplates and core wall of honey comb. The FEA results were obtained and graphs were plotted.
