C. W. SPICER, in a paper entitled Torsional Strength of Multiple-Splined Shafts,3 which was presented at the 1927 Semi-Annual Meeting, gave results of a number of tests which supplemented an earlier series of tests, conducted by him, directed toward the same object and previously reported.4
The results of these practical tests of actual splined shafts all indicate that, while the elastic-limit of the multiple-splined shaft is considerably less than that of a plain round shaft of diameter equal to the diameter of the splined shaft measured at the base of the splines, the ultimate-strength of the splined shaft exceeds greatly that of a plain round shaft of diameter equal to the base diameter of the splined shaft.
In the following analysis the authors approach the question from a purely theoretical standpoint indicating by analogy through their study, which applies only within the elastic range, that the low elastic-limit of the splined shaft may be readily accounted for by the high localized stress-intensity at the sharp inner-corners of the splines when the fillets there are omitted or made of small radius.
