Shearing or Compressing a Soft Glass in 2D: Time-concentration superposition

open access: yes, 2003
We report surface shear rheological measurements on dense insoluble monolayers of micron sized colloidal spheres at the oil/water interface and of the protein $\beta$-lactoglobulin at the air/water surface.

MICRO THERMAL ELASTOHYDRODYNAMIC LUBRICATION ANALYSIS OF LINE CONTACT ROLLER PAIRS CONSIDERING THE CHANGE OF ELASTIC MODULUS

open access: yesJixie qiangdu, 2021
As an important performance parameter of metal materials,the elastic modulus changes with temperature.However,in the analysis of thermal elastohydrodynamic lubrication,the elastic modulus has been taken as a constant,and there must be an error in the ...

The effect of the hydrogen coverage on the Young modulus of graphene [PDF]

open access: yes, 2012
We blend together continuum elasticity and first principles calculations to measure by a computer experiment the Young modulus of hydrogenated graphene. We provide evidence that hydrogenation generally leads to a much smaller longitudinal extension upon loading than in pristine graphene.

Theoretical study of the elastic and thermodynamic properties of Pt$_{3}$Al with the L1$_{2}$ structure under high pressure [PDF]

open access: yesCondens. Matter Phys., 2015, vol. 18, No. 4, 43601, 2015
In this work, the elastic and thermodynamic properties of Pt$_{3}$Al under high pressure are investigated using density functional theory within the generalized gradient approximation. The results of bulk modulus and elastic constants at zero pressure are in good agreement with the available theoretical and experimental values. Under high pressure, all
