Auxetic Materials for Sports Applications [PDF]

Procedia Engineering, 2014
AbstractIn this paper, the auxetic effect is introduced, the range of auxetic materials is briefly reviewed, and research demonstrating benefits having potential in sports applications is highlighted. These include the use of auxetic materials in impact protector devices (pads, gloves, helmets and mats) exploiting better conformability for comfort and ...

Progress of auxetic and semi-auxetic materials [PDF]

Engineering Review : Međunarodni časopis namijenjen publiciranju originalnih istraživanja s aspekta analize konstrukcija, materijala i novih tehnologija u području strojarstva, brodogradnje, temeljnih tehničkih znanosti, elektrotehnike, računarstva i građevinarstva, 2023
Auxetic materials with negative Poisson's ratios, display the unique behavior owing to their micro-structure or geometrical build. Auxetic materials resist deformities when subjected to uniaxial, biaxial, and shearing stresses. Cellular based materials are known for their excellent impact and shock energy absorption.

Study on the Size Effect of Auxetic Cellular Materials [PDF]

International Journal of Applied Mechanics and Engineering, 2017
The objective of this paper is to investigate the effects of scale of an auxetic cellular material sample on the evaluation of elastic properties. Size and boundary effects are studied in detail. This is achieved by conducting computer simulations of the auxetic structure under the typical loading exerted by the compression and simple shearing test ...

Auxetic metamaterials subjected to dynamic loadings [PDF]

Theoretical and Applied Mechanics, 2022
Materials with negative Poisson’s ratio are called auxetics and they present enhanced properties (e.g. damping, indentation resistance, fracture toughness and impact resistance) under external loadings.

(In)efficacy of architected auxetic materials for impact mitigation

International Journal of Impact Engineering
It has been demonstrated that auxetic materials, characterized by a negative Poisson’s ratio, offer enhanced resistance to indentation, shear forces, fracture toughness and the absorption of energy. As such, they are reported in literature to be promising options for impact mitigation in military and space contexts. Auxetic materials are rare in nature,

Compressive mechanical properties of ex-situ auxetic composite-filled tubes

Journal of Materials Research and Technology, 2021
Auxetic materials are a class of materials that expand transversely when stretched longitudinally. Recently, auxetic materials are gaining special interest in wide range of applications mainly due to their attractive mechanical behavior.
