Fatigue Testing - starting load
Fatigue Testing - starting load
(OP)
I am going to start carrying out some fatigue testing on a number of ferrous and non-ferrous alloys to produce S/N curves. Test parameters: tension-compression, fully reversed, Kt=1.
Could you please give me some advice on how to decide on which loads I should consider testing at considered to the material's tensile strength.
I thank you in advance for your assistance

RE: Fatigue Testing - starting load
It seems to me that to build an S-N curve you will need lots and lots of samples. Then you would test them at different stresses. Tehn plot stress vs CTF and at 10^7 cycles consider the DNF condition.
