Up to the present, many reports have been published about the stress concentration when materials have notches. But on the effect of the notch angle of V-shaped notch, few studies have been made. So we made many fatigue tests on specimens having V-shaped notches of various notch angles (from 0° to 180°) and fillet radii. From the result of the fatigue tests we derived the relation between notch factor β and notch angle θ or fillet radius ρ as follow : [numerical formula] where β is the notch factor at any value of notch angle θ, and (β)^<θ=0> is that at θ=0,and ρ is in mm.
