Basic Theory of Photoelasticity
The term “Photoelasticity“ *) describes methods of investigation and numerical evaluation of some mechanical quantities as strain, stress, mode of deformation, velocity distribution, etc..., in solid and fluid bodies by analyzing the change of state and velocity of electromagnetic radiation interacting with these bodies. The major methods of Photoelasticity are based on the analysis of induced and orientational birefringence by measuring the change of polarized radiant power transmitted or reflected from the body under observation.
