Elasticity of the Sm[1-x]Y[x]S alloy Based on Ultrasonic Measurements [PDF]

, 2016
The elastic moduli, sound velocities, Gruneisen parameter, Poisson's ratios and brittleness-plasticity criterion ratios are studied for the Sm[1-x]Y[x]S alloys. Their dependence on the concentration of alloy components including a valence transition from

Intrinsic Negative Poisson’s Ratio for Single-Layer Graphene [PDF]

Nano Letters, 2016
Negative Poisson's ratio (NPR) materials have drawn significant interest because the enhanced toughness, shear resistance and vibration absorption that typically are seen in auxetic materials may enable a range of novel applications. In this work, we report that single-layer graphene exhibits an intrinsic NPR, which is robust and independent of its ...

Negative Poisson’s Ratio in Single-Layer Graphene Ribbons [PDF]

Nano Letters, 2016
The Poisson's ratio characterizes the resultant strain in the lateral direction for a material under longitudinal deformation. Though negative Poisson's ratios (NPR) are theoretically possible within continuum elasticity, they are most frequently observed in engineered materials and structures, as they are not intrinsic to many materials. In this work,

Effects of heat exposure and volumetric compression on Poisson's ratios, Young's moduli and polymeric composition during thermo-mechanical conversion of auxetic open cell polyurethane foam [PDF]

, 2019
The effects of thermo-mechanical auxetic foam conversion parameters on the Young's modulus and Poisson's ratio of open-cell polyurethane foam are related to changes in chemical bonding and cell structure.

Fabrication of auxetic foam sheets for sports applications [PDF]

, 2017
Auxetic materials have a negative Poisson's ratio, which can enhance other properties. Greater indentation resistance and energy absorption, as well as synclastic curvature, could lend auxetic materials well to protective sports equipment and clothing ...

Controllable three-dimension auxetic structure design strategies based on triply periodic minimal surfaces and the application in hip implant

Virtual and Physical Prototyping, 2023
Based on the triply periodic minimal surface (TPMS), 3D auxetic structures are successfully implemented using a dual-period function. A series of shape-controllable, dual-period deformation functions are obtained by summarising the characteristics of ...
