Fatigue Limits

Fatigue Limits

(OP)
Does anyone know a source on the internet for fatigue limits of various stainless steels?  Matweb.com does not seem to have this information.  Thanks!

RE: Fatigue Limits

Can anybody inform me if you find any sites on web related with flexible machine elements such as belts, chains, flexible shafts ropes etc. I could be happy by this information. thanks...

RE: Fatigue Limits

(OP)
Although I haven't found a website with comprehensive fatigue/endurance curves, I will mention that I did find some curves in the Appendices of Section III of the ASME Boiler & Pressure Vessel Code (B&PVC).  Tables I.9.1, I.9.2, and so on, have such curves for various common materials.

But if anyone does find a website with this kind of information, I'm still interested.

RE: Fatigue Limits

Your'e best bet would be the "MIL-HNDBK-5".  This is the military material specs.  These are the only docs that I have seen that have the fatigue curves (S/N versus Stress)
Specs can be obtained from "Globe Engineering Documents"
Some curves are available from some manufacturers, you might try them.

RE: Fatigue Limits

I get all my MIL-Specs from http://assist.daps.mil/

It's free and most standards are there for download.  MIL-HDBK-5H is a huge .pdf file (42.5K) and takes quite a while to download.  I recommend downloading late at night.  Many times my download failed before I finally got it because of busy server activity, on their end and mine.

Enjoy,

Thanks!

RE: Fatigue Limits

There is another Web site for free downloading mil specs: http://astimage.daps.dla.mil/quicksearch/. I would suggest download a MIL-HDBK (usually big files) in segments, e.g. from page 1 to page 100, or by chapters one at a time, etc to avoid failures, etc.

Good luck!
