摘要：
The solutions for the problems of circular prismatic and glide dislocation loops in an infinitely extended linear isotropic non-local elastic medium are obtained assuming an appropriate three-dimensional non-local modulus. It is found that the stress fields have no singularities at the dislocation lines, in contrast to the classical elastic solutions. The stored elastic energy is estimated.
