Digital Simulation of a Circular Ring Loaded by a Diametric Compression for Photoelastic Analysis

Abstract

New phase unwrapping algorithm is verified for its performance in unwrapping the isoclinic parameter. Both numerical and experimental photoelastic fringes of the circular ring under compression are generated for unwrapping. Comparisons between the numerical and experimental results show that the phase unwrapping algorithm is robust regardless the presence of the singularities in the isoclinic map. This shows an advance of the phase unwrapping for solving the complex fringe patterns.
