Abstract
The paper deals with the strain energy consumed in fatigue failure under sinusoidal loading. The damage stress is considered, and it is shown that an energy formulation can be given for the traditional interpretation of the fatigue test results. That approach is used in determining the position of the French line, which it is suggested should be taken as the end of the crack initiation stage. The French line is constructed from the same data as used for constructing the fatigue curve.
