The dislocation structures of bulk textured and epitaxial thin film superconductors were examined. Correlations were noted between increases in flux-pinning and dislocation density. A model was presented for flux-pinning by individual dislocations. This provided a model for strain-induced effects and for the effects of normal state region interactions. It was shown that the predicted values of the pinning were in accord with experimental observations.
