Analysis on the Equivalent Elastics Modulus of a Novel Zero Poisson's Ratio Honeycomb Structure
A novel zero Poisson's ratio honeycomb structure is presented based on the star-shape honeycomb structure.The Struc-ture Genome Method(MSG)was employed to analyze the equivalent elastic parameters of zero Poisson's ratio honeycomb struc-ture.The equivalent elastic modulus was verified by the finite element method.The influences of the geometric parameters on the equivalent elastic parameters of the zero Poisson's ratio honeycomb were investigated.The results show that MSG has high accu-racy and efficiency in predicting the equivalent elastic parameters of honeycomb structures.The geometry dimensions of honey-comb structure have significant effect on the equivalent elastic parameters,which lower(1～2)orders of magnitude in-plane modulus compared with the raw material modulus.The novel honeycomb structure can maintain more stable zero Poisson's ratio for different structure dimensions.By comparing with the star-shape honeycomb structure,the ability of in-plane deformation and out-of-plane stiffness is better for the novel honeycomb structure,which has potential applications to morphing aircraft.
