Periodic Auxetics: Structure and Design [PDF]
The Quarterly Journal of Mechanics and Applied Mathematics, 2017 Materials science has adopted the term of auxetic behavior for structural deformations where stretching in some direction entails lateral widening, rather than lateral shrinking. Most studies, in the last three decades, have explored repetitive or cellular structures and used the notion of negative Poisson's ratio as the hallmark of auxetic behavior ...

Auxetics in smart systems and structures 2015 [PDF]
Smart Materials and Structures, 2016 Auxetics comes from the Greek (auxetikos), meaning 'that which tends to expand'. The term indicates specifically materials and structures with negative Poisson's ratio (NPR). Although the Poisson's ratio is a mechanical property, auxetic solids have shown evidence of multifunctional characteristics, ranging from increased stiffness and indentation ...

An Experimental Study of Auxetic Tubular Structures
Materials, 2022 Auxetic tubular structures are widely known structures, characterized by a negative Poisson’s ratio upon stretching and deformation in the axial and transverse directions, which have numerous application possibilities. In this paper, tubular structures were realized by rolling up planar auxetic structures and using rigid square frames as unit cells ...

Study of mechanical properties and enhancing auxetic mechanism of composite auxetic structures [PDF]
Engineering Reports, 2021 AbstractThe auxetic structures attract much attention because of their good properties, such as enhanced energy absorption capacity and buckling resistance. It is an important topic to combine the auxetic structures with other materials or structures to improve their mechanical properties.

A unified design method for 2D auxetic metamaterials based on a minimal auxetic structure
International Journal of Solids and Structures, 2023 Auxetic metamaterials are architected structures that possess a unique property known as a negative Poisson's ratio. This remarkable characteristic enables them to expand or contract in a direction perpendicular to stretch or compression. Due to their exceptional attributes such as energy absorption and fracture resistance, these auxetic metamaterials ...

Dynamic response of auxetic structures [PDF]
Vibroengineering Procedia, 2020 Auxetic materials have been investigated since the 1990’s, they are defined by a negative Poisson’s ratio which gives them interesting capabilities in energy and shock absorption. They are usually lattice structures (2D or 3D array of unit cells), which gives them high stiffness to weight properties and their properties can be tuned to suit a given ...

Cellular Auxetic Structures for Mechanical Metamaterials: A Review [PDF]
Sensors, 2020 Recent advances in lithography technology and the spread of 3D printers allow us a facile fabrication of special materials with complicated microstructures. The materials are called “designed materials” or “architectured materials” and provide new opportunities for material development.

DNA Nanostar Structures with Tunable Auxetic Properties
Molecular Systems Design & Engineering, 2023 ABSTRACT Auxetic structures are unique with a negative Poisson’s ratio. Unlike regular materials, they response to external loading with simultaneous expansion or compression in all directions, rendering powerful properties advantageous in diverse applications from manufacturing to space engineering. The auxetic behaviors are determined
