“…Figure 12 shows the relation between the stress concentration factor and flank angle for shafts with a 'V' groove under bending. The present equation is compared with numerical values by Murakami et al (22); they generally agree well. However, when 2p/D is 0.05 and 2t/D is 0.6, this equation gives values a little lower than the numerical values.…”

A new design equation for stress concentration factors is presented in this paper. This equation is an empirical equation and has been derived based on theoretical results of semi-infinite plates with a notch under tension and also numerical results of strips and shafts with finite notches under tension or bending. It gives stress concentration factors of notched strips and grooved shafts under tension or bending with one expression. This equation can be applied to various shapes of notches and loading conditions and is very convenient for a practical use. Values calculated by this equation are found to be closer to the numerical results recently published than those calculated by Neuber's formula.
