S = Fatigue Strength
N = Number of stress cycles

You'll need to tell us what branch of engineering you're talking about. Could be Signal to Noise if it's electronics.
Best I've found relating to friction in automotive application is SN=skid number (related to grip of tyres). In materials science, which it could conceivably also be, it seems to stand for Stress-straiN.

ehc11 has got the correct answer. You've got to be careful to take account of the mean stress, which isn't always stated on the S-N curve. I believe the basic curves are for cyclic stress about zero.

The only thing in my life SN ever represented was Student Nurse. Glad those days are over.
But I don't think that answers your question. Sorry.

I think its Stress Amplitude (S) against number of cycles to failure, used for fatigue analysis.
