Paper Abstract

An optical speckle shearing technique has been used to produce high quality displacement contours originating from out-of-plane displacement in plates of PMMA. An analysis of stress shows good agreement between the experimental and theoretical values. An electronic speckle shearing technique is being developed to provide on-line, 'real time' stress analysis.
