    • Dislocation (Surg) The act of dislocating, or putting out of joint; also, the condition of being thus displaced.
    • Dislocation The act of displacing, or the state of being displaced.
    • Dislocation (Geol) The displacement of parts of rocks or portions of strata from the situation which they originally occupied. Slips, faults, and the like, are dislocations.

Century Dictionary and Cyclopedia
    • n dislocation Displacement; derangement or disorder of parts.
    • n dislocation Specifically.
    • n dislocation In surgery: The displacement or separation of the parts of a joint; the unjointing of a limb; luxation. When dislocation takes place as the result of violence, it is called primitive or accidental; and when it happens as a consequence of disease, which has destroyed the tissues forming the joint, it is called consecutive or spontaneous. A simple dislocation is a dislocation unattended by a wound communicating internally with the joint and externally with the air; and a compound dislocation is a dislocation which is attended by such a wound.
    • n dislocation Anatomical displacement, as of an organ through disease or violence; malposition.
    • n dislocation In geology, a break in the continuity of strata, usually attended with more or less movement of the rocks on one side or the other, so that, in following any one stratum, it will be found to be above or below the place which it would have occupied had no break or dislocation occurred. See fault.
    • n dislocation The territorial distribution of an army.

A rib, a femur, or a thigh
Is but a dislocated sign
Of something hybrid, half and half
Betwixt a crocodile and calf--
Maybe a porcupine.
"The Antiquarian" by Hattie Howard

With a bullet in the tail-end of his spine

Who paints her housemaid's knees with iodine.

Ah! swing, ah! swing away! Can't afford to leave mah only,

Foh to steal mah Emmaleen, To dislocate mah happy home
And grab dis yellow queen.

In science:

We analyze stress-free dislocation walls in the continuum theory in section III, and connect them with Frank’s formula7 for the dislocation content of grain boundaries in appendix A.
Stress-free states of continuum dislocation fields: Rotations, grain boundaries, and the Nye dislocation density tensor
In the continuum dislocation theory a polycrystal is thus a stress-free configuration of dislocations.
Stress-free states of continuum dislocation fields: Rotations, grain boundaries, and the Nye dislocation density tensor
In section II, we derive the most general solution for the dislocation density tensor with zero stress.
Stress-free states of continuum dislocation fields: Rotations, grain boundaries, and the Nye dislocation density tensor
This would suggest that sharp, discrete wall formation is not implied by the energetics within the continuum theory; recent work elsewhere8,9 has shown that they may nonetheless form via shock formation in the natural dislocation dynamics.
Stress-free states of continuum dislocation fields: Rotations, grain boundaries, and the Nye dislocation density tensor
A dislocation is a crystallographic defect representing extra rows or columns of atoms and is characterized by two quantities; its line direction t, and its Burgers vector b.
Stress-free states of continuum dislocation fields: Rotations, grain boundaries, and the Nye dislocation density tensor
The Nye dislocation density tensor ρ is defined by ρ = (t ⊗ b)δ(ξ) where ξ is the two-dimensional radius vector measured from the axis of the dislocation in the plane locally perpendicular to t.
Stress-free states of continuum dislocation fields: Rotations, grain boundaries, and the Nye dislocation density tensor
The problem of finding a family of dislocation configurations with zero stress is equivalent to finding those densities eρ which are divergence free (iki eρij = 0) and are in the null space of K .
Stress-free states of continuum dislocation fields: Rotations, grain boundaries, and the Nye dislocation density tensor
As an example, consider a tilt boundary in the x-y plane constructed from a set of parallel dislocation lines pointing along the ˆx direction with the Burgers vector b pointing along the ˆz direction.

Let n be the number of dislocation lines per unit length along ˆy.
Stress-free states of continuum dislocation fields: Rotations, grain boundaries, and the Nye dislocation density tensor
But why is the tiltboundary stress free? Real grain boundaries have stresses from their constituent dislocations that cancel at long distances—they decay exponentially with distance over a length scale given by a typical distance between dislocations.
Stress-free states of continuum dislocation fields: Rotations, grain boundaries, and the Nye dislocation density tensor
Hence in the continuum limit where the dislocations become infinitely close together, the stress vanishes.

The fact that one needs two perpendicular sets of parallel dislocations comes out naturally in this formulation.

Because the number densities of the screw dislocations are the same in both directions, n here denotes the number density in one of the two directions.
