The effect of blemishes on the isochromatic fringe pattern in a stressed photoelastic model made from a "defective" photoelastic material such as an amine-hardened epoxy resin (Araldite CY 230-HY 951) was examined. Mottling decidedly distorted the fringe pattern while the entrapped air bubbles did not. The possibility of air bubbles causing perforations was very remote considering the size of the air bubbles vis-a-vis the specimen thickness for a 2-dimensional analysis which was quite often not <3mm. Similar results were obtained with single-edge-notch specimens.
