The interaction of a screw dislocation with a surface crack is analyzed in nonlocal elasticity under applied shear loading. The stress field is determined near the crack and the dislocation. The classical singularities at the crack tip and the dislocation core are eliminated. A maximum of the shear

The solution is given in closed form to the problem of the elastic field round a ~ dislocation an d a,. crack in any relative position when the field is independent of one of the three cartesian co-ordinates. The analysis holds for the most general anisotropy.
This paper presents the results of an analysis which considers the interaction between a semi-infinite crack and a dislocation dipole. Applying the operator derived by Denda [1] to the crack/dislocation interaction solution developed by Lo [2], explicit expressions are obtained for the stress intens
