Webb(1) The displacement of the crystal halves and the shear produced by the movement of dislocations are easily found. Consider a crystal of width L1 in the slip direction and thickness L, normal to the slip planes. If an edge type dislocation moves across the entire crystal it produces a displacement ?,. Webb14 aug. 2009 · Since dislocations “multiply” as they move (i.e., they increase their length), and since they are almost always present initially in structural materials, their most important property is their mobility.
