Auxetic materials expand in the lateral direction when stretched axially and contract laterally compressed axially, thereby resulting a negative Poisson's ratio. This counter-intuitive behaviour results such having very wide range of potential benefits as confinement improved bonding with cementitious matrices. phenomenon has resulted proliferation research use auxetic construction. However, numerous studies have focused on laboratory-scale composite samples for non-structural applications, while only few recent attempted to achieve full-scale structural elements. Studies continued be exploratory, variety reported findings together differing recommendations. paper, therefore, reviews state art application auxetics construction, challenges opportunities associated development these innovative materials, recommendations future encourage uptake by engineers. It examines more than 100 primary articles mechanical properties, design, optimisation, specific applications composites. An important finding from review is that derived reinforcements require deformations which far exceed serviceability limits specified elements static loading. Therefore, chosen geometry will bespoke design procedures satisfy both strength stiffness requirements, especially Furthermore, finite element modelling approach concrete damage plasticity also noted an essential tool analysing significant deformation structures.
