The macroscopic slip produced by the motion of an edge dislocation is shown in Fig. 11-9a and by a screw dislocation in Fig.11-9b.
Both the shear stress and final deformation are identical for both situations, but for an edge dislocation line moves parallel to the slip direction while the screw dislocation moves at right angles to it.
Recall the geometric properties of dislocations. This is summarized in Table 10-1.
