Abstract

A complete photoelastic stress analysis depends, in the majority of cases, on the accuracy of the fractional-fringe-order measurements. The error involved due to an error in the measurement of the isoclinic angle has been studied. It was found that the Tardy method was more accurate than the Sénarmont method, assuming negligible errors in the optical elements.
