Analysis of Stress using Photoelasticity technique -A Review

Mechanical Engineering

Photoelasticity is a non-destructive experimental method which is widely utilized for analysis of stress and strain value of complicated geometry of model and loading conditions. This experimental approach is based on birefringence effect of material. This method is very sensible as compared to the analytical methods considering mathematical steps which is a time-consuming method and unbalanced for examination. This method is widely used in various areas such as automotive, dentistry, civil and electrical field also. This review paper gives the information related to extent the photoelasticity technique has been explored in various fields of the various research and science. After reading and analyzing past work of photoelasticity experiment the effect of the increase of temperature due to different reasons based on a different kind of loading on the model has been neglected by the earlier researches paper. Also try to make, an elective polariscope is developed by using economical types of equipment for industrial purpose, for examination of stress field on the model or prototype.
