auxetic, and dilatational by later researchers. In this paper, the term 'auxetic' will be used. Since then, investigation on the auxetic materials has held major interest, focusing on finding more materials with negative Poisson's ratio, and on examining the mechanisms, properties and applications...
Auxetic materials are endowed with a behavior that contradicts common sense, when subjected to an axial tensile load they increase their transverse dimension. In case of a compression load, they reduce their transverse dimension. Consequently, these materials have a negative Poisson%26apos;s ratio in...
There are now different kinds of geometrical models for auxetic materials, such as re-entrant model, rotating model, nodule and fibril model, chiral model, liquid crystalline model, helical model and rod model for describing the angle-ply composites. Knitting technology, including plane and 3D warp...

Therefore, it is significant to design and manufacture tubular elements by using auxetic materials and structures [77]. Based on finite element analysis, the mechanical properties of NPR tubes have been investigated by Scarpa et al. [78] and Wadee et al. [79] initially. Scarpa et al. [80...

Auxetics referred to materials with negative Poisson’s ratio (NPR) [6], [39] and was first introduced by Evans in 1991 [40], playing an important role in MMMs [41]. This phenomenon is mainly attributed to their unique microstructure and composites designs [40], [42] and can improve ...
Auxetic structures are a special class of structural components that exhibit a negative Poisson’s ratio (NPR) because of their constituent materials,
