Abstract
Lattice models to describe the steady-state propagation of (i) a screw dislocation and (ii) a crack as a pileup of screw dislocations appear to be useful. This prompts us to exhibit a solitary wave equation whi ch describes the continuum limit of the lattice model of Celli and Fly tzanis for a screw dislocation. Some numerical consequences of this co ntinuum equation are also presented. (C) 1998 American Institute of Ph ysics.
