A COMPARATIVE ANALYSIS OF ORTHOTROPIC ELASTIC CONSTANT OF NOMEX HONEY COMB CORE

R. A. Pasha, T. Ahmed

Abstract


In this research work, the modulus of elasticity was determined by analytical and numerical means and correlated with experimental results for Nomex paper hexagonal honeycombs. The analytical methods included continuum formulations and models based on strength of materials including a variety of beam theories. The numerical method is used for determination of orthotropic mechanical properties of honeycomb core using Isotropic material properties of Nomex paper by FEA simulations using ANSYS as a tool, and the experimental testing consisted of mechanical characterization of the honeycombs under both in-plane and out-of-plane loading by using tensile testing. The results obtained are very useful and have close agreement.
