摘要

In this paper the crack path is studied for corner flaws in plates of finite thickness emanating from holes with different radius subjected to cyclic tension loading. Results show how the growing cracks tend towards a preferential propagation path and the convergence, closeness between the curves of crack growth, is quicker for higher Paris exponent and greater ratio of the hole radius to the plate thickness.
