TORSION OF ROUND SHAFTS WITH VARIABLE DIAMETER,

Abstract

A simple approximation method is shown for the calculation of stress increases at the transition points of stepped or grooved shafts. The results of this method are well confirmed by the paper of Willers as well as by our own experiments. This method depicts the actual conditions for practically all technically important cases with a completely sufficient accuracy. (The average error is less than =5%.) Somewhat larger deviations -- meaning higher computed maximum stresses -- will probably result for exceptionally abrupt transitions, i.e., in cases which are obviously dangerous and are therefore in practice of minor interest only, apart from the fact that they can always be avoided.
