Abstract

Conventional honeycomb structures show positive Poisson's ratio under in-plane loading while Auxetic honeycombs show negative Poisson's ratio. Accordion, Hybrid and Semi re-entrant honeycomb structures show zero Poisson's ratio, i.e. they show zero or negligible deformation in lateral direction under longitudinal loadings. In this paper an FEA analysis of these three types of structures is made using commercial software ANSYSR 14 using 8 node 281 shell elements. Cell wall thickness and cell angle is varied to analyze their effect on elastic modulus Ex and global strains along X direction under X-direction loadings. Ey is also analyzed to measure lateral stiffness and deformation behavior of structure for its potential application as flexures.
