Towards RGB photoelasticity: Full-field automated photoelasticity in white light
TLDR
A new full-field method for the automatic analysis of isochromatic fringes in white light, named RGB photoelasticity, which makes it possible to determine retardations uniquely in the range of 0–3 fringe orders.Abstract:
In this paper a new full-field method for the automatic analysis of isochromatic fringes in white light is presented. The method, named RGB photoelasticity, eliminates the typical drawbacks of the classical approach to photoelasticity in white light which requires a subjective analysis of colors and an experienced analyst to acquire and interpret the results.read more

Boundary extraction and polarimetry in translucent specimens for photoelastic stress analysis
TL;DR: In this article, the problem of providing input to a novel method of interpreting photoelastic data for performing experimental stress analysis of models of engineering components is addressed, where the authors use the direction of the principal stresses in the specimen (isoclinic data) along with the difference in principal stresses (isochromatic data).

Applicability evaluation of the stress-optic law in Newtonian fluids toward stress field measurements
TL;DR: In this paper, the authors studied the stress-optic law for the flow-induced birefringence that appears in shear flows of a Newtonian fluid, containing tiny flake-structured particles which align in the local shear directions.
