## Abstract From a survey of the literature and experimental results obtained with two austenitic steels it is concluded that for fatigue crack propagation with negative R‐values the often used relation Ξ”K~eff~ = K~max~ underestimates the crack growth rate. Relations between Ξ”K~eff~ and Ξ”K are pres

The Gaussian stationary stochastic load process is considered to cause fatigue crack growth in randomly inhomogeneous materials. The Paris-Erdogan model is applied and the time when the crack length reaches a critical value (lifetime) is determined as a random variable. It is shown that random varia
