• V-notch
• Short crack
• Screw dislocation
• Mode-III stress intensity factor

A concise and precise formula for mode-I stress intensity factor of a short crack emanating from the bisector of a V-notch has been derived by Philipps et al. The crack tip stress intensity factor is directly evaluated via the mode-I generalized stress intensity factor of an uncracked notch. This note further supplements an accurate formula to calculate mode-III stress intensity factor for a short crack emanating from a V-notch.
