Auxetics are materials or structures which exhibit negative Poisson’s ratio and expands perpendicular to the force applied. Nowadays, they are currently used in fabrics, foam like products and its usage is limited. In literature, several works have been carried out to analyze the properties and behavior of these materials in various conditions. In this work, stents based on different auxetic structures were modelled and analyzed using finite element analysis. The Chiral, Re-entrant and Rotating unit type of auxetic structures were modelled. The Poisson’s Ratio and Young’s Modulus are the performance metrics considered to analyze these structures. The Magnesium Alloy AZ61 is the material chosen to make the stent bio absorbable. Results suggest that chiral auxetic structure-based stent of this material produce appreciable results in terms of the performance metrics considered.
