The decrease in stress intensity factor, expected from dislocation emission at a crack tip. can be achieved either through a change in crack tip radius (blunting) or through a crack closure induced by the dislocation (shielding) opposite to the opening imposed by the external stress field. So an app
## Abstract Based on results of a previous paper [1] a general formula for the development of the shape of surface cracks is presented. In case of tension an analytical solution is presented, which allows a very easy parameter study. For other loading conditions solutions can be obtained, using num
