The Characters of KI and KII in Notched Beam
The distributions of stress intensity factor KI and KII in notched beam specimens have been obtained in this paper by researching on internal force distributions, photoelastic experiments and statistics from numerical results. Two approximate formulae of KI and KII have been constructed. A simple and correct way to calculate KI and KII of beam is provided.
