Digital photoelasticity – A comprehensive review
TLDR
This review thematically classifies all the developments in digital photoelasticity and highlights the relative merits and drawbacks of the various techniques to allow an end-user to make an informed choice on the type of technique to be used in a particular situation.Abstract:
Digital photoelasticity has rapidly progressed in the last few years and has matured into an industry-friendly technique. This review thematically classifies all the developments in digital photoelasticity and highlights the relative merits and drawbacks of the various techniques. The overall objective is to provide enough information and guidance to allow an end-user to make an informed choice on the type of technique to be used in a particular situation.read more

One-dimensional local binary pattern based color descriptor to classify stress values from photoelasticity videos
Juan Carlos Briñez de León,Domingo Mery,Alejandro Restrepo-Martínez,John Willian Branch Bedoya +3 more
TL;DR: The one-dimensional local binary patterns (1D-LBP) are used to describe such color variations and use them to identify the stress values they belong and make categorical stress maps from a photoelasticity video itself, which significantly opens new opportunities to simplify the experimental and computational operations that limit the stress evaluation process in line with the dynamic experiment.

Mechanical analysis of square shaped PMMA using reflection photoelasticity
TL;DR: In this article, an application of reflection photoelasticity used to analyze stressed samples was presented, which showed isochromatic and isoclinic fringe patterns in a poly(methyl methacrylate) sample.

Fourier fringe analysis: the two-dimensional phase unwrapping problem.
TL;DR: A new phase unwrapping algorithm is described that uses local phase information to mask out those parts of the field that cause inconsistencies in the unwraps and can produce an approximately correct unwrapped.

Towards full field automated photoelastic analysis of complex components
Eann A. Patterson,Z F Wang +1 more
TL;DR: The design of a automated system for photoelastic analysis of complex components and the potential of the system for providing detailed data over the full field of view is demonstrated by the analysis of a slice from a model of a bolt.

Demodulation of a single interferogram by use of a two-dimensional regularized phase-tracking technique
TL;DR: A two-dimensional regularized phase-tracking technique that is capable of demodulating a single fringe pattern with either open or closed fringes and gives the detected phase continuously so that no further unwrapping is needed over the detectedphase.
