It is difficult to solve the problem of stress-strain distribution in plastic regions in comparison with elastic regions. Thus, an attempt to expand and apply stress-strain analysis by photoelasticity, has been promoted so far and many significant achievements have resulted therefrom.
Photoplasticity is a full-field technique that is based on the interpretation of optical patterns in transparent birefringent materials that have been stressed beyond their elastic limit.
Polycarbonate resin, a photoplastic model material, has been subjected to much study. In this paper, we attempted to survey of recent photoplastic experimentation.
