In order to clarify the effects of notches on yielding, strain figures devloped in notched shafts are observed in details during the plastic stage of elastic-plastic torsion. The test pieces used are 0.48% C carbon steel shafts having a Sled Runner keyseat; keyseat fillet, with keyseat end away from shoulder fillet; and with n Sled Runner keyseats. The torsional moment-deflection curves are obtained throughout the elastic-plastic stage of torsion and the values of torsional moment are obtained for each notch. Constraint factors for each notch are given and the influence of the shape of notch on the factors is investigated. Comparison is made with the theoretical results obtained previously in the case of yield condition of constant maximum shearing stress.
