In this study, photoelastic epoxy universal joint model was made by duplicating the configuration of real automobile joint. Several types of specimens with different diameter of center hole which contributes to reduce the weight were machined. Stress caused by input torque was frozen inside specimens during stress freezing procedure. Stress concentration of the universal joint with and without a center hole subjected to torsion was analyzed by the photoelastic stress-freezing method. The results were compared with the finite element analysis, and good accordance was observed. The maximum tensile stress increased as the diameter of center hole increased. The tensile stress appeared on the outer surface was found to be always greater than that appeared on the hole's surface. Transition of the area which the maximum tensile stress appeared from trunnion's neck to boss was observed as hole's diameter increased.
