thanks for that metengr.
The only reason I asked is that the fatigue of welded specimens in only propagation, and region 2 of fatigue crack growth da/dn curve is propagation??
metengr,
thank you for your reply, I have made alot of use of this site previously and find it very useful. However I cant find the answer to my question.
davefitz,
just to confirm, you are saying 'Yes, your observation is correct' to my question of the slope of an s-n fatigue curve is = to...
I am looking into the fatigue behaviour of welded joints of MIG welded C-Mn/HSLA structural steel. It is common knowledge that the S-n curves of welded joints exhibit a distinct slope ~1/3 (and i have results of load controlled tests supporting this, nothing new). I am on the understanding that...
