Phase unwrapping method for three-dimensional stress analysis by scattered-light photoelasticity with unpolarized light. 2. Experiment
Abstract
A phase unwrapping method that employs scattered-light photoelasticity with unpolarized light was proposed for automated three-dimensional stress analysis [Appl. Opt. 45, 8848 (2006)]. I now demonstrate the validity of this method by performing nondestructive measurements at three different wavelengths of the secondary principal stress direction {psi}j and the total relative phase retardation {rho}jtot in the plane that contains the rotated principal stress directions in a spherical frozen stress model and compare the results obtained with mechanically sliced models. The parameters {psi}j and {rho}jtot were measured nondestructively over the entire field of view for the first time, to the best of my knowledge.
