“…With this discovery, researchers started to realize that these materials had a vast number of applications. Since then, a whole range of synthetic auxetic materials have been produced for all major classes of materials, such as metals, ceramics, polymers, and composites (16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34). However, natural auxetic materials do exist, examples being single crystals of arsenic (35) and cadmium (36), α-cristobalite (37), and many cubic elemental metals (38).…”

Developments in design and technology in the engineering and medical fields necessitate the use of smart and high-performance materials to meet higher engineering specifications. The general requirements of such materials include a combination of high stiffness and strength with significant weight savings, resistance to corrosion, chemical resistance, low maintenance, and reduced costs. Over the last three decades, it has been demonstrated that auxetic materials offer a huge potential for the fields of engineering, natural sciences, and biomedical engineering, and for many other industries, including the aerospace and defense industries, through their unique deformation mechanism and measured enhancements in mechanical properties. To meet future engineering challenges, auxetic materials are increasingly being recognized as integral components of smart and advanced materials. Although materials with a negative Poisson's ratio have been known since the early 1900s, they did not capture researchers' attention until the late 1980s. Since 1991, these materials have been known as auxetic materials. Since then, their benefits and applications have been expanded to all major classes of materials such as metals, ceramics, polymers, and composites, and they are also now being used in engineering applications. The goal of this review was to present the development of auxetic polymers, which were first fabricated in the form of polyurethane foam approximately three decades ago and are now used in the fabrication of non-woven nano/ micropolymeric structures. This review could provide useful information for the future development of auxetic polymers.

“…Consequently, a negative Poisson's ratio plate attains synclastic deformation when pure bending is applied on two opposing sides -unlike conventional plates, which exhibit anticlastic deformation. Arising from these anomalies, negative Poisson's ratio materials have been investigated for a number of mechanical and physical characteristics such as fatigue [3], impact properties [4], transport/diffusion properties [5], contact deformation [6], plastic failure [7], and electromagnetic properties [8], to name a few. Further understanding of the various properties of negative Poisson's ratio materials was sought via homogenization techniques [9], numerical methods [10], molecular modeling [11] and classical techniques [12] among others.…”

In micromechanical modeling of composites, it is well known that the Voigt formula or the rule-of-mixture method gives the most general upper bound estimate of the effective Young's modulus. In this article it is shown that the effective longitudinal Young's modulus of a continuous unidirectional fiber composite significantly exceeds the rule-of-mixture when both constituents possess equal or almost equal Young's moduli and opposing Poisson's ratio signs.

“…Chen and Feng [40] investigated the dynamic response of laminated plates with auxetic layers. Shil'ko et al [41] examined the self-locking effect upon contact deformation of isotropic and anisotropic auxetic materials (having a negative Poisson ratio). Li et al investigated sandwich plates with a functionally graded auxetic 3D lattice core using the FE simulations and experiments for the nonlinear dynamic response [42], large-amplitude vibrations [43], nonlinear bending [44], and postbuckling behavior [45].…”

Mechanical Stability of Eccentrically Stiffened Auxetic Truncated Conical Sandwich Shells Surrounded by Elastic Foundations

et al. 2022

View full text Add to dashboard Cite

The static stability of auxetic truncated conical sandwich shells reinforced by stiffeners surrounded by elastic foundations is investigated. The shells are made from two isotropic outer layers and an auxetic core layer with a negative Poisson ratio. Based on the classical shell theory, combined with the displacement and Bubnov-Galerkin methods, the governing equations of the shells are derived and solved. The critical buckling load of the shells as a function of their geometrical parameters, the honeycomb structure, stiffeners, and types of elastic foundations are examined in detail.
