In the previous paper, we invented the method to separate principal stresses by using only the isochromatic fringe patterns. In the present paper, by using this method, we propose an automatic stress analysis system by photo-elasticity. This system is composed of the photo diode, the amplifier, the A-D converter and the computer. The analogue information on the isochromatic fringe patterns is coverted to the digital one by the photo diode, the amplifier and the A-D converter. Thus, by using the microcomputer involved the program to separate the principal stresses, we obtain the stress distributions from these digital data of the fringe patterns. We apply this system to obtain the stress distributions of the circular and square plates subjected to concentrated loads, and show that the stresses obtained by the present system are in good agreement with those calculated theoretically or given by Frocht.
