Abstract

Using the concept of prescribed arrays of point forces and point couples, the long range displacement, the stress and the interaction energy fields associated with an isolated volume defect in nonlocal micropolar continuum elasticity are calculated. It is shown that all the physically possible volume defects can be described by a distribution of body forces and body couples. Interestingly these forces and couples are not singular extending therefore the validity of the classical continuum treatment of defects. Line defects such as dislocations and disclinations can be analyzed in a similar way.
