The influence on the crack growth rate for a short edge crack under fatigue loading due to changes in crack length, grain size, load range and grain boundary configuration, is investigated under quasi-static and plane strain conditions. The geometry is modelled by distributed dislocation dipole elem

The propagation of short cracks in the neighbourhood of grain boundaries have been investigated using a technique were the crack is modelled by distributed dislocation dipoles and the plastic deformation is represented by discrete dislocations. Discrete dislocations are emitted from the crack tip as

## a b s t r a c t In this study, the growth of a short edge crack during more than 14 000 cycles of fatigue loading is investigated in detail. An edge crack, in a semi-infinite body with no pre-existing obstacles present, is modelled in a boundary element approach by a distribution of dislocation
