Fatigue Curves or S/N Curves 3

Does anyone know where I can get any fatigue or S/N curves???

Books, websites etc....

I would ideally like to find curves rather than the data as I finding that usually a limited number of samples have been taken to aquire the data, whereas curves are formed from lots of samples not just a couple of dozen samples.

In particular aluminium alloys and stainless steel curves would be more useful-but any fatigue curve for any material would be grateful.

Many thanks in advance
Steve

Steve,

ASM International, a materials-oriented professional society, is the best source of this type of data. I would recommend you investigate the following publications that they offer:

ASM HANDBOOK Volume 19: Fatigue and Fracture

Atlas of Fatigue Curves

Properties of Aluminum Alloys: Tensile, Creep, and Fatigue Data at High and Low Temperatures

Fatigue Data Book: Light Structural Alloys

You can find out more (pricing, availability, etc.) at their website:

http://www.asminternational.com

A good source of fatigue data is the U.S. Government, specifically the military. MIL-HDBK-5H, Metallic Materials and Elements for Aerospace Vehicle Structures, has a lot of fatigue data. It is available for free at the following website:

http://astimage.daps.dla.mil/quicksearch/

Note: this is an absolutely HUGE file (> 42 MB), so it takes forever to download. You should only attempt this if you have a T1 line or a cable modem, and a very robust connection.

Another military publication is the Aerospace Structural Metals Handbook, which is published by the U.S. Air Force.

Some or all of these publications would be available at a major university library, so I would recommend a trip if you don't want to pay a lot for this info. I doubt you will find much fatigue data on any of the internet. Best of luck to you.

 

TVP, the download problem you mention above for MIL-HDBK-5H is resolved if you use

and select "MIL-HDBK-5H." (The pop-ups are killed if you turn off javascript, called "Scripting" in IE, in your browser options.) You can pick any subsections you need at the above link and save a huge amount of wasted time.

f61,

Thanks for the info. Since I already have the document this doesn't help me, but I'm sure it will be of benefit to Steve and others.

MIL-HDBK-5 is also available at this site, broken down by chapter, reducing download time.
