Abstract

Materials used structures that undergo impact in various applications such as helmets that are used in sports and mining applications, bumpers in cars and space vehicles, play a major role in protecting human life and structures. In this paper, we present the design of auxetic structure, which can sustain more impact when compared to conventional structures. Auxetic structures have negative Poisson's ratio which aids them to behave in a different way. These structures contract (expand) transversely under uniaxial compression (tension). Auxetics is a term used to describe materials and structures that have this property. A comprehensive review of previous auxetics research is presented, covering diverse auxetic cellular models, naturally observed auxetic behaviour, various desirable auxetic features, and potential applications. In this study, the deformation behaviour of auxetic re-entrant structure is compared with conventional structures to know the behaviour of auxetic structures. Various structures are analysed using FEA software such as Ansys and Abaqus Explicit for different application purposes. This paper proposes the possibilities of developing new sustainable structures for use in absorbing impact structures in mining and automobile, among other possible applications.
