Abstract

Abstract: The recent advances in digital photoelasticity have made it possible to use it conveniently for the stress analysis of articles and components made of glass. Depending on the application, the retardation levels to be measured range from a few nanometres to several thousand nanometres, which necessitates different techniques and associated equipments. This paper reviews the recent advances in the photoelasticity of glass with a focus on the techniques/methods developed in the last decade. A brief introduction to the residual stress in glass is provided initially to bring out its tensorial nature. The subsequent sections are organised thematically rather than chronologically, for better readability and easy access of information. Highlights: Reviews advances in photoelasticity of glass with a focus on research in last decade. Methods for stress measurement in flat, axi-symmetric and generic 3D glass problems are discussed. Discusses glass stress analysis using transmission, scattered light and integrated photoelasticity. Tensorial nature of the residual stress in glass is brought out.
