FRANK-READ MECHANISM

frank
Cisailt
A dislocation segment pinned at both ends is bowing out under an applied resolved shear stress. The resulting Frank Read mechanism is at the origin of dislocation multiplication in the DDD simulations. Plastic steps are printed on the free surfaces when dislocations escape the crystal. Colors indicate the local shear stress induced by the dislocations.
