| Abstract: | In this paper, the determination of stress intensity factor of a V-notch by photoelastic method is presented. It is shown that the data of isoch-romatic fringe order should be measured in y direction and its neighbourhood. The photoelastic pictures are suggested to be magnified 50 times. The factors K1 are then calculated according to equation ( 4 ) . |
