In comparing a material's resistance to distort under mechanical load rather than to alter in volume, Poisson's ratio offers the fundamental metric by which to compare the performance of any material when strained elastically. The numerical limits are se

This data suggests that the FN networks we engineered formed an incompressible material with a Poisson’s ratio of ~0.5. While the Poisson’s ratio of cells and other biological materials are widely estimated as 0.5, our experimental results demonstrate that for FN networks this is a reasonable ...
A method of measuring the Yong's modulus, Poisson ratio, and coefficient of thermal expansion (CTE) is presented. The method uses a wafer curvature technique to measure thermal stresses of thin films of the same material deposited on two different substrates, one isotropic and the other thermome...
Poisson’s ratio is an elastic constant that measures the compressibility of material perpendicular to applied stress, or the ratio of latitudinal to longitudinal strain. For regular rocks, the Poisson’s ratio ranges from 0.20 to 0.35, and is very sensitive to the composition of rocks. According...
Similar with coefficient of thermal expansion, Poisson's ratio is also an intrinsic parameter that characters the ratio of the transverse and longitudinal strains of materials. Generally, as shown in Fig. 1b, most of the conventional engineering materials such as alloys, ceramics, concrete, glass,...
Monolayers of layered materials, such as graphite and molybdenum dichalcogenides, have been the focus of materials science in the last decades. Here, we reveal benign stability and intriguing physical properties in the thinnest monolayer wurtzite (wz) se
Materials with a negative Poisson’s ratio, also known as auxetic materials, exhibit unusual and counterintuitive mechanical behaviour—becoming fatter in cross-section when stretched. Such behaviour is mostly attributed to some special re-entrant or hin
