Fatigue curves

Hi all,
do someone know where I can download some S-N curves for fatigue (Wohler curves) ?
Just some examples like one or two steels, one or two aluminium...etc

Thanks.

Thanks for your response Irwin.
I would like to know if there an internet site where I can download S-N curves of basic materials as examples.
But it would be great if someone could give us examples with S-N curves they have.

Could u detail what are the sd,k,Nd parameters ?

Thx

philcondit,
The chapter9 has only the 9.1 section...but S-N curves are behind this point.
I didn't find a SN curve in the previous chapters... do you have some explanation ?

Thanks

Cavic,

Seach for MIL-HDBK-5 on the internet. Or search material supplier sites.
