TL;DR: In this article, a review of existing photo-orthotropic clasticity theories under three major headings stress-optic laws strainoptic law and approximate strain-optical law is presented.
Abstract: The development of the theory of birefringence of annotropic composites has proceeded mainly along the following directions, strew strain models, analogy, integrated photoelasticity and tensonal nature of birefringence. All these studies have concluded that three independent photoelastic constants are needed to characterize orthotropic model materials. In the literature, there has not been uniformity of notation used in the representations of the results. In this paper, using uniform notation, existing photo-orthotropic clasticity theories are reviewed under three major headings stress-optic laws strain-optic laws and approximate strain-optic laws. The interrelation ships between stress-optic and strain-optic coefficients are brought out Interpretation of isoclinics is discussed. The steps necessary to calibrate a birefringent orthotropic composite are summarized and finally the influence of residual birefringence is also discussed.
