Abstract
An expression of the cumulative failure probability of a structure is proposed for cyclic loading conditions. This expression is dependent on the initial flaw distribution and on the microcrack propagation law. Two independent sets of experiments were carried out on specimens made of Spheroidal Graphite cast iron. These specimens were tested under cyclic tension with different load ratios. The initial flaw distribution and the propagation law parameters are identified from the first set of experimental results. The expression of the failure probability is then used to predict the second set of experimental data. The effect of the load ratio is discussed and the influence of stress field heterogeneity is studied.
