The elastic interaction between an edge dislocation and a loop in BCC systems

We have evaluated the interaction between an edge dislocation and a loop in BCC metals. In this calculation, we used the linear elastic theory to estimate their long range interaction, and we incorporated the change in the normal vector of the loop in the stress field originating from the edge dislocation. The rotation of the loop significantly modifies the interaction and strongly affects the microstructural evolution and the irradiation hardening.
