This paper develops a fracture mechanics model of the impact endurance of graphite. The model, based on crack growth, defines the probability of failure for a material with an inherent flaw variability, subjected to repeated impacts of different magnitude chosen randomly from an applied stress distribution. A special experiment was mounted on a particular graphite to test the general model. The predicted performance using the model gave a good description of the experimental behaviour. The relatively small differences observed are attributed to statistical uncertainties associated with both the experiment and the data on which the model is based. © 1985.
