► This review puts emphasis on their aspects of mechanics and computations. ► Auxetic materials are technologically and theoretically important and fascinating. ► Up until now, the research has been dominated by periodic/ordered microstructures. ► The future is with disordered microstructures using homogenization method. This paper summarizes research work related to materials with zero, or negative Poisson’s ratio, materials which are also referred to as auxetic materials. This review puts an emphasis on computations and aspects of their mechanics. It also considers diverse examples: from large structural, to biomedical applications. It is concluded that auxetic materials are technologically and theoretically important. While the development of the research has been dominated by periodic/ordered microstructures, the author predicts that future research will be in the direction of disordered microstructures utilizing the homogenization method.
