Two kinds of the as-received and the heat treated structural steel, the nickel-chromium alloy and the copper alloy were selected for this investigation. The rolling contact fatigue test, the pulsating compression fatigue test and the completely reversed torsion fatigue test were conducted. The relationships of the fatigue limit among the rolling contact fatigue, the pulsating compression fatigue and the completely reversed torsion fatigue were examined on the basis of the experimental observation. Consequently the fatigue limit P0 under the rolling contact fatigue test could be estimated from the tensile strength σB, the yield stress σy and Young's modulus E as P0=0.07σB√(E/σy. )
