The demand for lightweight structures made of sandwich panels is ever increasing in many industrial sectors World over numerous researches are actively pursued on several aspects of sandwich structures Sandwich panels consist typically of two thin face sheets and a lightweight thicker core The core provides low density relatively high out of plane compression stiffness and shear properties These panels find wide application in public transport industry aeronautical sectors building industries, tooling machines and serigraphy newlineHoneycomb sandwich panel consists of core in the shape of repeated hexagonal unit cells of light weight material and bonded with face sheets at top and bottom Aluminum Honeycomb Core Sandwich AHCS panels are fabricated using aluminum sheets for core and face sheets AHCS panels with A3003 grade aluminum is considered in this study as it is widely used for light weight structures Based on the geometrical features of the AHCS panels constitutive equations have been evolved theoretically to predict sandwich panel density core compression strength crushing strength shear strength in longitudinal and transverse directions flexural rigidity core shear modulus and stiffness newline newline newline%%%reference p185-164.
