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

On the first boundary value problem of the photoelastic thin ring
Djelloul Rezini,Tawfik Tamine +1 more
TL;DR: In this article, the results obtained from the hybrid method developed in this paper, are applicable to any irregular shaped photoelastic domain of interest, and the correctness of the results for the circular ring is confirmed and discussed in details.

Optical method for identification and quantification of full-field stress distributions and evolution in assembled lining structures based on additively printed models and phase-shifting methods
TL;DR: In this paper , a plane-stress-model-based photoelastic testing method was developed for direct observation and quantification of the full-field stress distribution and evolution in an assembled lining structure based on additive manufacturing or three-dimensional printing technology and phase shifting methods.

A new method for extracting the full-field dispersion data of birefringent objects based on the digital RGB-photoelasticity
Mohammed S. Raslan,T.Z.N. Sokkar +1 more
TL;DR: In this paper , the point-wise distribution of the dispersion data of birefringent materials is analyzed using the well-known digital photoelasticity technique, which can be applied to profile the data in three dimensions during static, online, real-time, and dynamic investigations.

Novel Scanning Scheme for White Light Photoelasticity
TL;DR: A novel scanning scheme is proposed whose progression is guided by the spatial resolution of the isochromatic fringe pattern and encapsulates the noise within the zones of low spatial resolution and eliminates their propagation.

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.
Journal ArticleDOI
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.
