Different from conventional materials, materials with negative Poisson's ratios expand laterally when stretched longitudinally. Known as ‘auxetic’ materials, the effect means they possess particularly fascinating properties, which have recently attracted considerable attention in the literature. A range of auxetic materials has been discovered, theoretically designed and fabricated. Developments in additive manufacturing (AM) techniques enable fabrication of materials with intricate cellular architectures. This paper outlines recent progress in the development of auxetic materials and structures, and their mechanical properties under quasi-static and dynamic loading are analysed and summarised. Limited experimental studies on 3D printed auxetic materials and structures are given more attention, ahead of extensively finite element (FE) simulations. A special focus is dedicated to their large, plastic deformation behaviour and energy absorption performance, which should be stressed in their engineering applications; no review paper has yet been found regarding this. Finally, this paper provides an overview of current study limitations, and some future research is envisaged in terms of auxetic materials and structures, nano-auxetics and additive manufacturing.

与常规材料不同，泊松比为负的材料在纵向拉伸时会横向扩展。这种效应被称为“膨胀”材料，意味着它们具有特别令人着迷的特性，最近在文献中引起了极大关注。已经发现，理论上设计和制造了多种膨胀材料。增材制造（AM）技术的发展使制造具有复杂蜂窝结构的材料成为可能。本文概述了发展性材料和结构的最新进展，并对它们在准静态和动态载荷下的力学性能进行了分析和总结。对3D打印的膨胀材料和结构的有限实验研究受到了更多关注，领先于广泛的有限元（FE）模拟。特别要注意它们的大的塑性变形行为和能量吸收性能，这在它们的工程应用中应予以强调；尚未找到与此相关的评论文件。最后，本文概述了当前的研究局限性，并设想了一些未来的研究，涉及的材料包括：声学材料和结构，纳米声学和增材制造。
