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

On the effects of a crack propagating toward the interface of a bimaterial system
TL;DR: In this paper, the influence of matrix cracks on the failure mode of bimaterial systems and composite materials was investigated by using systematic numerical simulations, and the numerical results have permitted to implement simple formulas that allow the user an accurate evaluation of the SIF as well as to predict possible debonding or fiber splitting phenomena.

An improved normalization technique for white light photoelasticity
K. Ramesh,Ashutosh Pandey +1 more
TL;DR: A novel normalization methodology is developed to improve the dynamic range in both low and high fringe density areas and it is demonstrated that while applying normalization for stretching the dynamicrange, one has to use only an experimentally recorded calibration table that is normalized.
