Stress Optical Coefficient, Test Methodology, and Glass Standard Evaluation

Abstract

The photoelastic behavior of transparent materials under stress, which is represented by the material property of stress optical coefficient, can be used to evaluate glass samples of known and unknown composition. Using a polariscopic and load frame, we were able to create and observe the conditions of stress-induced birefringence. A modification of an ASTM testing procedure for determining stress optical coefficient is described. Stress optical coefficient data for several types of glasses are computed for comparison and standardization purposes.
