Modelling of fatigue crack growth at the microstructural level
Source abstract
Abstract
Abstract Since the 1960s we have used the stress intensity parameter K to characterise the growth of fatigue cracks. More recently it has been demonstrated experimentally that this parameter does not work for small cracks: these cracks tend to grow faster than would be predicted using linear elastic fracture mechanics, they show lower threshold values for growth, and the one-to-one relationship between growth rate and stress intensity range breaks down. One reason for this behaviour is that these cracks are of the same order of size as the microstructure––typically
