Hi,
Is there anyone familiar with this machining operation? I am struggling to find any information on the Internet, maybe it is known with another name but I am bit lost at the moment.
Thanks for your help.
Dear spring experts,
Every mechanical handbook provides equations to calculate the torsional stress at the coils of a helical compression spring, corrected for the curvature effect via the Wahl factor. But it is known that not all coils participate to the same extent to the load bearing action...
Hi everybody,
I am struggling to find an analytic solution for the stress concentration due to a 3-D ellipsoid.
This article from Sadowsky and Sternberg dating back to 1949 dealt with the problem, and I tried to reproduce the same trend with the aid of a symbolic computation tool.
There must...
