Taking advantage of some recent closed form expressions for the stress distributions due to V-notches with end holes, the micro-structural support factor, s, to apply the Fictitious Notch Rounding (NFR) approach, is evaluated by adopting a normal stress criterion. The closed form expressions for the micro-structural support factor (s) as well as for the fictitiously enlarged end radius (rho(f)), provided here for the first time, highlight the crucial role played by the notch opening angle for this notch configuration.
