DESCRIPTION:"F.C. Frank. Proc. Phys. Soc. A 62\, 131 (1949). ":http://iops
 cience.iop.org/0370-1298/62/2/307\n\nIt is shown that when a Burgers screw
  dislocation moves with velocity v it suffers a longitudinal contraction b
 y the factor (1 - v2/c2)1/2\, where c is the velocity of transverse sound.
  The total energy of the moving dislocation is given by the formula E=E0/(
 1 - v2/c2)1/2\, where E0 is the potential energy of the dislocation at res
 t. Taylor dislocations behave in a qualitatively similar manner\, complica
 ted by the fact that both longitudinal and transverse displacements and so
 und velocities are involved.\n
