Hi, anyone can advise what is Stress Amplification Factor (SAF) and its difference between Stress Concentration Factor (SCF)?
Thank in advance.

The change in local peak stress divided by the change in the stress at the reference point (SAF) was calculated for each increment using a threee point cnetral difference formula.

The FEA study was on an assembly of 2 threaded steel pipes. SAF was calculated for various points on the thread under different load conditions, like bending, tension, etc.
It's quite straightforward that a point with higher SAF is more critical. What else can we tell from SAF?
Any comment?

However, just to make sure that I understand correctly:
The above statement (regarding zero SAF for plastic flow) is based on a perfectly plastic assumption, correct?
It sounds like, for all intents and purposes, the SAF is equal to the stress concentration factor for linear-elastic problems.
