We find difficulties to determine the value of the notch factor in machine-design, in spite of many experimental results have been shown. In this report, I attempt to determine some proper value of these notch factors from my experimental results under rotating-bending stress, for U, V and rectangular notches-single, double, and tripple circumferential groove on the circuler shaft. In the U, V notches, the experimental results shows that the notch factor is proportional to the degree of stress concentration, but in the case of rectangular notches, the value of the factor is lower than that estimated from the stress concentration in the groove corner, obtained from photo-elastic experiments.
