Peterson's Stress Concentration Factors, 2nd Edition?
unclesyd, I found that one in my search. It doesn't have the geometry I need. I also found it to work in a very different manner than I understand (it uses Kn, Kg, K..., while I use Kt which is then converted to Kf). But I also ran some tests with it, and it gave stresses that seemed far too...- MarkEIT

Bolted Joint Stress Calculation
Cockroach, I know you have it right, but so does niravpshah. "...and if the ratio of stress to allowable is LESS THAN 1 then the design is okay." ... stress/ stress allowable is 1/(FofS), which would require a value less than '1' to be safe. However, I know what you're saying. Usually people...- MarkEIT

Peterson's Stress Concentration Factors, 2nd Edition?
Thanks Allen. I have a confession to make. I went to talk to my boss about potentially buying this book, and he pulled it off the shelf for me... he had it all along. Rather than bumping the thread up to say, 'don't bother' I figured it was dead anyway. But thanks for the effort! :)- MarkEIT

Why are involute splines involute?
I don't know why I couldn't find any of that! I did do a web search, and found nothing. I thought the involute profile was expensive to produce. I guess with the amount of development that has gone into it, it must be a lot cheaper now. Thanks for that!- MarkEIT

Why are involute splines involute?
The two splines fit together (male and female). The fit is going to be pretty good. If there is any slippage (perhaps from alternating loads), it'll tend to make the spline teeth slide relative to one another, meaning that there is sliding contact. Which goes against the reason to make...- MarkEIT

Why are involute splines involute?
Just a general question. Why are involute splines 'involute'? I can understand gear teeth being involute, so that the contact area of the two gear teeth does not move relative to one another. But involute splines do not rotate relative to eachother, so why does the spline profile have to be...- MarkEIT

Peterson's Stress Concentration Factors, 2nd Edition?
I am currently using the first edition to do fatigue analysis on rotating shafts. There are several stress risers that do not have charts in the first edition. I'm wondering if someone who has the second edition can tell me if they are covered in it. 1 - Snap ring grooves, with flat bottoms...- MarkEIT
