Research output: Contribution to journalArticlepeer-review


In the paper, stochastic description of curvilinear fatigue crack growth is provided. The crack growth process is regarded as a cumulative random jump process consisting of a random number of random increments with random angles. The probability distribution of the crack size represented by the model is determined and the relation of the basic model parameters to fracture mechanics is analyzed. The description presented seems to be capacious enough to include various realistic situations resulting in departure of crack growth from the straight-line direction.
