The approach takes a basis of the local statistical parameters of the logarithms of fatigue lives at the reference load. According to an assumption that the material constants in each relation are concurrently in same probabilistic level, the curves is described by a general form of mean and standard deviation curves of the logarithm of fatigue life, in which four material constants are at most contained.
