The elastic fields of a circular prismatic dislocation loop in a two‐phase material are evaluated to arrive at the elastic energy and Peach‐Koehler force. The results can be expressed in terms of complete elliptic integrals. The asymptotic forms reveal that the interaction between the prismatic loop and the second phase is not necessarily restricted to simple repulsion or attraction, and that for certain combinations of the elastic constants stable or unstable equilibrium positions are possible.
