Investigation on Effects of Geometric Parameters on the Negative Poisson’s Ratio of a Reentrant Structure

Ling, Yiru


It is not common to find negative Poisson’s ratio in nature but it exists in auxetic materials. The auxetic property enables the material to elongate in both vertical and horizontal directions under tension. Cellular honeycombs with repetitive reentrant cells are a common example of auxetics. This thesis investigates the geometric impacts of a reentrant structure originating from honeycombs on the negative Poisson’s ratio of the structure. Finite Element Method is used for the simulation, with...[Show more]
