NEGATIVE POISSON’S RATIO AND PERCOLATING STRUCTURES [PDF]
Elastic properties of non-uniform, two-component systems are studied in frames of a model of percolation on a simple cubic lattice. It is shown that as the ratio of the bulk moduli of the components tends to zero, ϰ = Ks/Kh → 0 (where s, h denote the ...

Fracture energy of high-Poisson's ratio oxide glasses [PDF]
International audienceThe apparent relationship between Poisson's ratio and fracture energy has been used to guide the discovery of ductile glasses with a brittle-to-ductile (BTD) transition at Poisson's ratio around 0.32.

Continuous measurement of apparent Poisson's ratio for yarn based on omni-directional diameters [PDF]
We proposed a new method for measuring apparent Poisson's ratio for yarn and developed a new tensile tester equipped with a digital micrometer that can measure the omni-directional diameter of the yarn annularly while the yarn is elongated.

One of the issues that modern implants face is their high stiffness, coupled with a positive Poisson’s ratio along the implant. This creates certain problems with bone inflammation and implant detachment.

Estimation of the Poisson's Ratio of the Rock Mass [PDF]
The value of Poisson's ratio is a crucial parameter in rock mechanics and engineering for both intact rock and rock mass. Poisson's ratio has not gotten the attention it merits compared to other essential mechanical characteristics of intact rock and ...

The origin of negative Poisson's ratio in rutile-type oxides and fluorides is explored through density functional theory (DFT) simulation. The study highlights the dominant role of nearest-neighbor central force interactions, thereby inspiring the design

The Poisson’s Ratio of enamel, dentin and dental restoration materials
The Poisson ratio and the Young’s modulus form a pair of independent material constants of solids. For hard tooth tissues the Poisson’s ratio should correspond to the Poisson’s ratio of restorative materials in order to avoid overstresses at the border ...

In this study, nanocellulose aerogels with a tunable Poisson’s ratio were fabricated. Tissue engineering scaffolds with a tunable Poisson’s ratio may be better able to simulate the mechanical behavior of natural tissues. A mixture of cellulose nanofibers
