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

Defense hole design for a shear dominant loaded plate
TL;DR: In this article, the authors designed an optimum Defense Hole System (DHS) for a large plate with a circular hole in shear dominant-load range, which reduced the stress concentration associated with circular holes for tensile/shear ratio ranging from 0% to 25% by 13.5% to 16.67%.
