The present work studies the size-dependent surface stress, surface stiffness, and Young’s modulus of a prism crystalline nanowire, which is theoretically treated to be composed of a hypothetical nanowire phase, a true two-dimensional geometric surface phase, and a true one-dimensional geometric edge phase. The hypothetical nanowire phase could be elastically deformed due to relaxation of a
Young''s modulus — Wikipedia Republished // WIKI 2
The technical definition is: the ratio of the stress (force per unit area) along an axis to the strain (ratio of deformation over initial length) along that axis in the range of stress in which Hooke''s law holds. Units Young''s modulus is the ratio of stress (which has units of pressure) to strain (which is dimensionless), and so Young''s modulus has units of pressure.
Silicon Carbide Ceramics has superior rapid cooling and rapid heating resistance, wear resistance, oxidation resistance, high bending strength, no falling slag, no crazing, have a long time service life, effective to control the uniform temperature inside the kilns and maintains high mechanical strength in temperatures as high as 1700 C. .

Estimation of Young’s Modulus of Graphene by Raman …
The Young’s modulus of graphene is estimated by measuring the strain applied by a pressure difference across graphene meranes using Raman spectroscopy. The strain induced on pressurized graphene balloons can be estimated directly from the peak shift of the Raman G band. By comparing the measured strain with numerical simulation, we obtained the Young’s modulus of graphene. The …
Young''s modulus - formulasearchengine
Young''s modulus, also known as the tensile modulus or elastic modulus, is a measure of the stiffness of an elastic material and is a quantity used to characterize materials. It is defined as the ratio of the stress (force per unit area) along an axis to the strain (ratio of deformation over initial length) along that axis in the range of stress in which Hooke''s law holds.
