A closed-form analytical solution was obtained for the stress field of a circular Volterra dislocation loop which had glide and prismatic components. By assuming that the material was linearly elastic and infinitely isotropic, the stress field was found by line integration of the Peach-Koehler equation for a circular dislocation loop. The field equations were expressed in terms of complete elliptic integrals of the first and second kinds. According to the superposition principle, the general loop solution was the sum of the prismatic and glide solutions. The stress solution which was obtained was compared with stress calculation results for segmented loops (6 to 24 segments) which had the same radius. It was concluded that such comparisons would be useful for checking new dislocation-dynamics simulations which discretized some form of curved dislocation line.
