Abstract :
An auxetic material is one which gets fatter when it is stretched. Thus, unlike most materials, it has a negative Poisson´s ratio. This review looks at examples of auxetic materials, the effect the negative Poisson´s ratio has on their mechanical properties and how these fascinating new materials can be used in applications as diverse as smart fasteners, replacement blood vessels and curved car door panels. It also considers the benefits of introducing such novel effects in undergraduate teaching
