Residual stress evaluation using shearography with large shear displacements
Second International Conference on Photomechanics and Speckle Metrology: Speckle Techniques, Birefringence Methods, and Applications to Solid Mechanics; Moiré Techniques, Holographic Interferometry, Optical NDT, and Applications to Fluid Mechanics, 1991A newly developed optical method for the qualitative and quantitative evaluation of residual and live-load stresses is presented. The method utilizes shearography employing a large angle shearing prism which results in large shear displacements. The large angle shearing prism allows the surface speckle pattern to be referenced and mapped onto a remote,

Facile displacement of citrate residues from gold nanoparticle surfaces
Journal of Colloid and Interface Science, 2018The stability of citrate-residues on gold nanoparticles (AuNPs) against ligand displacement has been controversial. Using AuNPs synthesized with deuterated citrate in combination with in-situ surface-enhanced Raman spectroscopic (SERS) analysis, we report that both citrate-residues and solution impurities can be simultaneously adsorbed onto citrate ...

RESIDUAL DISPLACEMENT DUE TO ARBITRARY PLASTIC STRAINS
International Journal of Modern Manufacturing TechnologiesThe displacement of the boundary of an elastic body in which inelastic strains exist or initiate due to various conditions can affect the intended functioning of the machine element and thus the service life of the assembly. Plastic strains are often initiated when the body is loaded beyond the elasticity limit of its material.
