“…Stimulated by the many intriguing properties and practical applications discussed above, the investigation of materials with negative Poisson's ratio has attracted considerable interest. So far, enormous progress (as summarized in Figure ) has been made in realizing a negative Poisson's ratio in various advanced materials, such as organic materials, mixed‐valence materials, oxides, low‐dimensional films, and man‐made materials ranging from the macroscopic level (honeycombs, foams, ceramics, composites, or others) down to the microscopic level (microporous polymers, molecular auxetics, and low‐dimensional materials). In previous reviews, attention has mainly been focused on man‐made synthetic materials with special structures (as shown Figure ) spanning from the molecular level to the macroscopic scale .…”

Materials with negative Poisson's ratio attract considerable attention due to their underlying intriguing physical properties and numerous promising applications, particularly in stringent environments such as aerospace and defense areas, because of their unconventional mechanical enhancements. Recent progress in materials with a negative Poisson's ratio are reviewed here, with the current state of research regarding both theory and experiment. The inter-relationship between the underlying structure and a negative Poisson's ratio is discussed in functional materials, including macroscopic bulk, low-dimensional nanoscale particles, films, sheets, or tubes. The coexistence and correlations with other negative indexes (such as negative compressibility and negative thermal expansion) are also addressed. Finally, open questions and future research opportunities are proposed for functional materials with negative Poisson's ratios.

“…In most of the works, very different models of 2D microstructures of auxetic materials (often verified experimentally) are presented, both at the molecular and the macroscopic level, see, e.g., Refs. . Much more difficult models of microstructures for the 3D auxetic materials have been proposed in Refs.…”

Using both mathematical and numerical methods, the optimal distributions of material characterized by the Young modulus and Poisson ratio (as well as other moduli of isotropy) maximizing the overall stiffness of an inhomogeneous isotropic elastic 3D body transmitting a given surface loading to a given support are constructed. The overall stiffness of the body is defined as the inverse of the work of external forces on displacements, called here the compliance of the structure. The isoperimetric condition bounds the integral of the trace of the Hooke tensor. It is proved that isotropic composite materials forming the bodies of extremely high stiffness exhibit negative Poisson ratio in large subdomains, which points at the significance of the auxetic material in modern structural design. The obtained results show that the whole range of possible variation of the Poisson ratio is used, from −1 to 1/2, which proves usefulness of the auxetic materials.

“…For example, high positive Poisson's ratio and negative Poisson's ratio foam and cellular filler materials can be designed using topology optimization of microstructural materials [46]. Additive manufacturing technologies have allowed producing such auxetic materials effectively [47,48]. The Poisson' ratio studied here will be of considerable potential for future practical applications in energy absorbers.…”
