I'm doing a fatigue analysis on a threaded fastener. It's 1-14UNS-3B
threaded, and experiencing an axial force and a bending moment. I'm
using 2.8 for the stress concentration (it's a higher grade fastener
with rolled threads). However, I'm having trouble with estimating the
notch sensitivity. I'm probably being way too concervative with .8 as
the radius of the thread is probably much smaller than .01". Any
insights or advice?
Thanks in advance,
Dave
