Paper Abstract

An automatic stress analyzer from photoelastic fringes using personal computer is developed. The photoelastic fringes are taken in by TV camera. On the basis of the image processing, the isochromatic fringes are extracted, and the fringe orders are determined. The principal stresses are separated with the combination of the sum of principal stresses calculated by the finite element analysis of Laplace's equation and the difference of principal stresses obtained experimentally from the isochromaic fringes. The results obtained are put out to monitor TV, printer, plotter and disk unit. The analyzer developed is low-price, easily operated, and suits to analyze stresses within the whole domain under consideration.
