Auxetic materials for bioprostheses [In the Spotlight]
IEEE Signal Processing Magazine, 2008 In this paper, the properties of auxetic materials, their biomedical (bioprostheses) and signal processing applications are discussed. Materials with negative values of the Poisson's ratio (NPR) are referred to as auxetic.

Elasticity of Auxetic Materials
, 2023 The auxeticity of elastic materials is described and explained by the use of the linear and nonlinear models of elastic deformations for a wide range of strain values up to moderate levels. This chapter consists of three parts – general information on auxetic materials, description of auxetics by the model of the linear theory of elasticity ...

Revealing Rutherfordine Mineral as an Auxetic Material [PDF]
Applied Sciences, 2018 The mechanical behavior of the uranyl carbonate mineral, rutherfordine, UO2CO3, was studied by means of theoretical solid-state methods based in Density Functional Theory using plane waves and pseudopotentials. The results of the computations reported in this work show that this mineral exhibits the important negative Poisson ratio (NPR) phenomenon. In

Load Distributing Metamaterials Via Discrete Optimization
Advanced Functional Materials, EarlyView.Mechanical metamaterials are computationally optimized to homogenize transmitted forces by minimizing the spread of reaction forces. The resulting architectures transform localized loading into broader, more uniform force distributions and experimentally demonstrate robust load spreading under quasi‐static and impact loading.

Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials
Advanced Materials, EarlyView.Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

Re-addressing the role of knitted textile design knowledge: auxetic textiles from a practice-led, designer-maker perspective [PDF]
, 2014 This study reacts to the segregation of knowledge and practice surrounding weft-knitted textiles, their design and applications. This study challenges current disciplinary practices that divide knit into scientific, design and art areas by describing a ...
