stress concentration factor in splines
i would like to know what's "out there" for stress concentration factors in splines. the closest thing i could find was in st. peterson's book that deals with scf's in gear teeth.
check out our whitepaper library.
in peterson's stress concentration factors, second edition by pilkey, a value of 2.8 is given in section 5.3 (splined shafts in torsion).
three definitive sources for calculation methods of splines:
(1) din 5466-1 splined joints, calculation of load capacity - part 1: general basis
(2) din 5466-2 splined joints - calculation of load capacity - part 2: splined joints according to din 5480
these are german language only, and available from din at:
thanks... i finally found the same information in peterson's book (1974) in chapter 5 section b page 248 - 249. i went through the calculations (from peterson) and analyzed the spline as an involute gear. for the particular geometry i analyzed, i got a scf = 2.39 as compared to the published scf = 2.8 for a spline in peterson's book. so i guess i was at least in the same ballpark. that's good to know; and thanks again.
