slip
in engineering and physics, sliding displacement along a plane of one part of a crystal relative to the rest of the crystal under the action of shearing forces-that is, forces acting parallel to that plane. Much of the permanent, or plastic, deformation of materials under stress is the result of slip within the individual crystals that constitute the material. Slip and an alternate mode of deformation, twinning, are the only ways that crystals in solids can be permanently deformed. In slip, all the atoms on one side of the slip (or glide) plane do not slide simultaneously from one set of positions to the next. The atoms move sequentially one row at a time into the next position along the plane because of structural defects or spaces, called edge dislocations, in the crystal that move at the same rate in the opposite direction.
