The Refraction Indices and Brewster Law in Stressed Isotropic Materials and Cubic Crystals

open access: yesCrystals, 2021
We study the elasto-optic behavior of stressed cubic crystals (all classes) and isotropic materials (like e.g., glasses). We obtain the explicit dependence of the refraction indices on the stress (either applied or residual), as well as a mild ...

Measurement of Stress Optical Coefficient for Silicone Adhesive Based on Terahertz Time Domain Spectroscopy

open access: yesPhotonics, 2022
The bonding structure is affected by environmental loads during use, causing internal stress in the adhesive layer, which leads to the debonding and expansion of the bonding layer.

Improvement of Fourier Polarimetry for applications in tomographic photoelasticity [PDF]

open access: yes, 2006
The use of the Fourier Polarimetry method has been demonstrated to extract the three characteristic parameters in integrated photoelasticity. In contrast to the phase-stepping method, it has been shown that the Fourier method is more accurate.

Evaluation of stress intensity factor of multiple inclined cracks under biaxial loading

open access: yesFracture and Structural Integrity, 2012
A finite rectangular plate of unit thickness with two inclined cracks (parallel and non parallel) under biaxial mixed mode condition are modelled using finite element method. The finite element method is used for determination of stress intensity factors

Electron-phonon interaction via Pekar mechanism in nanostructures [PDF]

open access: yes, 2004
We consider an electron-acoustic phonon coupling mechanism associated with the dependence of crystal dielectric permittivity on the strain (the so-called Pekar mechanism) in nanostructures characterized by strong confining electric fields. The efficiency
