Three-dimensional interactions of a circular crack with dipoles, centers of dilatation and moments

Exact solutions in elementary functions are derived for the stress intensity factors of a circular crack interacting with various stress sources : dipoles, moments, centers of dilatation and rotation. Such stress sources may model defects like vacancies, foreign particles, dislocations. Locations and orientations of the stress sources with respect to the crack are arbitrary.
