In this research, the compressive behavior of structures consisting of two types of cells were studied (honeycombs and re-entrant), in order to know the effect of the ratios of these cells on the mechanical properties of the structures. In addition, by controlling the Poisson’s ratio with a constant Young’s modulus, three types of structures (traditional honeycomb, auxetic and zero Poisson’s ratio (ZPR)) were obtained together with the ability to control their mechanical properties without changing the geometric properties of the cell. Numerical models were created and compared with the results obtained from the structures manufactured by the 3D printer experimentally, and where the Young’s modulus, Poisson factor and compressive deformation were close to the experimental results. In this current research, new structures have been proposed by incorporating traditional honeycomb cells with auxiliary honeycomb cells into a single structure without changing the cell geometry. The aim was to control the Poisson’s ratio in order to obtain all types of structures mentioned above without changing the geometric properties of the cell.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
