No slip has taken place to the left of AD, and therefore AD is a dislocation line.
Thus, the dislocation line is parallel to its Burgers vector, or slip vector, and by
definition this must be a screw dislocation. Consider the trace of a circuit around

58 FORCES ON DISLOCATIONS When an external force of sufficient magnitude
is applied to a crystal, the dislocations move and produce slip. Thus, there is a
force acting on a dislocation line which tends to drive it forward. Figure 515 ...

to the dislocation line. As a result, the force on a dislocation is not necessarily in
the same direction as the applied stress. All of the equations for the strain energy
of a dislocation in Sec. 57 were expressed per unit length of dislocation.
