Material properties can be tailored through modification of their geometry or architecture. With this concept, a lot of smart materials, metamaterials, and smart structures have been developed. Auxetic materials and structures are a novel class of materials which exhibit an interesting property of negative Poisson's ratio. By virtue of the auxetic behavior, mechanical properties such as fracture toughness, indentation resistance, etc., can be improved. In order to exploit the interesting properties of auxetic materials, several potential applications of auxetic materials have been explored in medical, sports, automobile, defense, etc. Design and modeling of novel auxetic materials and structures is still on the way. Here, the article focuses upon the different aspects of auxetic materials and structures. A comprehensive updated review of auxetic materials, their types and properties, and applications has been presented. This paper also discusses the design and modeling approaches of auxetic structures.

“…The NPR property of auxetic materials offers several advantages such as the enhancement of shear stiffness, plane strain fracture toughness, and indentation resistance . An improvement in these properties confers a great potential to the auxetic material to be used in a broad range of applications, which include biomedical fields, personal protective equipment, garment, crash boxes, vehicle, and aircraft seats, anti‐vibration gloves and others . It has been shown in crashworthiness applications, for instance, that despite a slight increase in the peak load, the auxetic foams may improve the majority of crashworthiness indicators such as energy absorption, specific energy absorption, and crush force efficiency .…”

This paper describes the fabrication of polymeric auxetic foam using a quasi tri-axial compression method. In this method, the conversion process is executed by applying a quasi tri-axial compression on conventional closedcell polyurethane foams. In order to achieve optimum auxetic characteristics, the densification points in various directions are evaluated. In addition, the heating time of the compressed foam is also determined and applied to minimize the residual stress due to the volumetric compression. It leads to the fabrication of auxetic foams with achievable maximum re-entrancy and minimum collapsed cells without surface creasing. The results also show that the optimized auxetic foam exhibits isotropic behavior compared to its precursor foam as verified by the morphological analysis. The produced foam has all the desired properties of auxetic foams. The auxetic foam with a negative Poisson's ratio may have a great potential as the supplementary materials in energy absorption and structural applications.

“…The auxetic metamaterials could deform without the beam or wall buckling and achieve stable negative Poisson's ratio at large strain levels. Smardzewski et al [21] developed numerical models of auxetic compression springs suitable for seat structures of office and home furniture. Analyses were conducted on real and numerical models of different spring structures subjected to uniaxial compression.…”
