5. Glissile Dislocation Loops - (15 points) Consider a glissile [110] dislocation loop of radius "R" on the (111) plane in Cu that is in equilibrium with an external shear stress r. (a) (3 points) Would the dislocation loop be circular or elliptical? Justify your answer. (b) (10 points) Calculate the shear stress required to expand the loop for the case when "R"=50nm take both the interaction force and the Peierls stress into account. (c) (2 points) What would happen if the external stress was removed? Justify your answer.
