The extraction of the singularities in the wrapped map of the isoclinic parameter photoelasticitally obtained is presented. The method involves the use of two wrapped maps of isoclinics and a map of modulated intensity. Two characteristics-the abrupt phase jumps around the singularities and the values of modulated intensity-are used to identify those positions. The technique developed herein is evaluated with the real phase maps of an eccentrically loaded split ring (C-shaped model) under compression and experimental results are also presented.
