Abstract

The flatwise compressive behavior of tetrachiral and hexachiral honeycombs is analysed, using analytical and Finite Element simulations, both with explicit and implicit formulations. The Tetrachiral and hexachiral cells are composed by cylinders connected by 4 and 6 tangent ligaments respectively. The ligaments act as mixed stiffeners- elastic foundations during flatwise compressive loading, providing different buckling mode shapes during deformation. The models are compared with experimental results obtained using RP-based honeycombs tested according to ASTM C 393-00 and ASTM C365-00
