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

Optical method to quantify the evolution of whole-field stress in fractured coal subjected to uniaxial compressive loads
TL;DR: In this article, the authors presented an optical method to reveal and quantify the continuous evolutions of the whole-field principal stress difference and shear stress in fractured coal by combining 3D printing technology and digital photoelasticity.
Journal ArticleDOI
Robust multidirectional smoothing of isoclinic parameter in digital photoelasticity
TL;DR: Three methods for noise removal of isoclinic data calculated using a plane polariscope are proposed using an outlier smoothing algorithm and progressive multidirectional progressive smoothing is found to be effective in removing the noise at lower as well as at higher loads.

Residual Stress Analysis of Commercial Float Glass using Digital Photoelasticity
Ramakrishnan Vivek,K. Ramesh +1 more
TL;DR: In this article, a methodology involving carrier fringes in conjunction with digital photoelasticity is used to quantify the residual stress in float glass, and the results are verified by six-step phase-shifting technique (a subset of ten-stage phase shifting method) using an automatic polariscope.

Metrological considerations in the measurement of contact stress parameters using photoelasticity
TL;DR: In this paper, it is shown that these limitations no longer apply when using the Generalized Least Squares by Lagrange Multipliers (GLMM) method, which can be used to measure the parameters that characterize the contact stress field.

A. Vivekanandan,K. Ramesh +1 more
TL;DR: In this paper, the effect of an interacting internal crack on the edge crack in a transient thermal stress field is evaluated using digital photothermoelastic experiments and finite element (FE) analysis.

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.
