A Stress Freezing Procedure for Less Photoelastic Model Distortion
Although the stress-frozen photoelastic technique provides an excellent and ingenious method for three-dimensional stress analysis in photoelasticity, there are some cases in which the distortion of the stress-frozen models is remarkable due to the considerably low modulus at the freezing temperature, leading to an unignorable error in the stress distribution.
