How to Determine Maximum RPM of a Spinning Disc?

[mechdesignron]

Hello,

I would like to know how to determine the max RPM of a disc. I would think it would be the centrifugal force against the Yeild Strength. Any help would be appreciated.

Thanks,
Ron

What you're looking for is something called disk burst. It's a preliminary design tool for turbines and other rotating components.

As far as what the limit is, well then it depends on your design criteria. If you're looking for the point where the disk explodes, then you'll want to look at rupture strength or ultimate.
