Stress intensity factors for deep cracks emanating from the corner formed by a hole intersecting a plate surface [PDF]
A technique consisting of freezing photo-elasticity and a numerical method was used to obtain stress intensity factors for natural cracks emanating from the corner at which a hole intersects a plate surface.

Application of Photoelasticy for Study of Lamellar Cracks. [PDF]
In rolled sheets, non–metallic inclusions are distributed along the thickness of the sheet as narrow lines running parallel to the rolling direction. Such inclusions are the nuclei of lamellar cracks.

Full-field pulsed-magneto-photoelasticity - a description of the instrument
This paper describes a novel instrument used for the analysis of full-field through-thickness stress distributions using the theory of magneto-photoelasticity (MPE) developed by Aben and Clarke et al. [ , , ].

Principal stress and strain trajectories in non-linear elastostatics [PDF]
The Maxwell-Lame equations governing the principal components of Cauchy stress for plane deformations are well known in the context of photo-elasticity, and they form a pair of coupled first-order hyperbolic partial differential equations when the ...

Stress Analysis in Glass Artwork
A simple method for determining the stress fields in transparent glass artwork pieces is presented. The proposed method is based on the principles of photoelasticity combining imaging and quantitative measures with an image processing algorithm. The main

Photoelastic coupling in gallium arsenide optomechanical disk resonators
We analyze the magnitude of the radiation pressure and electrostrictive stresses exerted by light confined inside GaAs semiconductor WGM optomechanical disk resonators, through analytical and numerical means, and find the electrostrictive force to be of ...

Microwave Photoelasticity: A Resonant Wavelength Approach Applied to PEEK Polymer [PDF]
Every nondestructive testing (NDT) technique has its unique set of advantages and limitations. Currently, the only existing noncontact NDT method capable of measuring sub-surface stresses, in optically opaque materials, at near-real-time speeds and over ...
