Investigating Effect of Geometrical Parameters on Negative Poisson’s Ratio of S-shaped Auxetic Structure
Abstract
Auxetic material is developed to trim down weight and upsurge strength of the matter, which
leads to negative Poisson’s ratio. Current research is focused on auxetic strength, hence in this
work parametric influence of S-shaped unit cell on Poisson’s ratio is explored and results are
compared with finite element analysis. Parameters like Angle, Thickness and Aspect ratio are
compared and concluded that they have individual significance on Poisson’s ratio. The
S-shaped auxetic structure is analysed and proves that negative Poisson’s ratio is a function of
wall thickness, angle and aspect ratio.
