(OP)
Hello,
Has any one idea how I can proceed to do the fatigue test of leaf spring in order to obtain the S-N curves?
Thanks

RE: fatigue test
decide a load to apply,
apply the load and release,
contiue until failure,
count the number of cycles.
if you're doing only one test, divide by 10 for safe life, if you're testing (say) 5 specimens, divide test life by 5.
altenatively, if you Really want an S/N curve ... test a gizzillion specimens (yes, that is the technical term) of different stress concentrations, cycle forms (min/max) of the leaf spring material.

But yes, the more simulations you run, the more accurate your results.

If you want to test your actual article, that's a different question as RB implied. I would suggest you find the fatigue life analytically rather than by test. But, if a test is required for QC or other reasons, RB's suggestion looks okay as a quick estimate. Examine the requirements for your actual program/industry.
