Photoelasticity of crystalline and amorphous silica from first principles

, 2003
Based on density-functional perturbation theory we have computed from first principles the photoelastic tensor of few crystalline phases of silica at normal conditions and high pressure (quartz, $\alpha$-cristobalite, $\beta$-cristobalite) and of models ...

RGB photoelasticity applied to the analysis of membrane residual stress in glass [PDF]

, 2011
The measurement of residual stresses is of great relevance in the glass industry. The analysis of residual stress in glass is usually made by photoelastic methods because glass is a photoelastic material.

Can an increase in abutment screw length enable biomechanical advantages for implants with increased crown height space?

Journal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this finite element analysis (FEA) study was to investigate how screw length and crown height affect the stresses generated in the implant‐abutment complex and alveolar bone for anterior single implants and whether the use of longer abutment screw would compensate for increased stresses originated from increased crown ...

Photo-elasticity of silk fibroin harnessing whispering gallery modes

Scientific Reports, 2023
Silk fibroin is an important biomaterial for photonic devices in wearable systems. The functionality of such devices is inherently influenced by the stimulation from elastic deformations, which are mutually coupled through photo-elasticity.

3D mechanical analysis of aeronautical plain bearings: Validation of a finite element model from measurement of displacement fields by digital volume correlation and optical scanning tomography [PDF]

, 2010
On Airbus aircraft, spherical plain bearings are used on many components; in particular to link engine to pylon or pylon to wing. Design of bearings is based on contact pressure distribution on spherical surfaces.

Effect of substructure fabrication method and design on the fracture resistance properties of metal–ceramic restorations

Journal of Prosthodontics, EarlyView.
Abstract Purpose In metal–ceramic restorations, the substructure fabrication method and design may affect the prognosis of the prosthesis. This study evaluated and compared the fracture resistance of metal–ceramic restorations fabricated with different substructure fabrication methods using two different alloy powders and designs.

Optic Axis Rotation and Bertin Surface Deformation in Lead Tungstate (PWO) and Other Tetragonal Crystals by Stress and Misalignment of Crystallographic Cells: A Theoretical Study

Crystals
For tetragonal lead tungstate (PWO) and other tetragonal crystals, we study modifications of the Bertin surfaces induced by either the distortion of crystallographic cells, the applied plane stress, or cell misalignment with respect to the specimen faces.

A Lightweight Skin‐Adhesive Fiber Bragg Grating Sensor to Advance Minimally Invasive Healthcare Monitoring

Advanced NanoBiomed Research, Volume 6, Issue 2, February 2026.
A novel self‐adhesive hydrogel matrix is engineered to embed a fiber Bragg grating sensor for real‐time monitoring of physiological strain signals. The developed system conforms to the skin without external supports and, thanks to the fiber–matrix mechanical coupling, captures both subtle and large‐scale deformations.
