Computer simulation of plastic deformation through planar glide in an idealized crystal
The behavior of the plastic deformation of an idealized crystal made by stacking parallel slip planes is reported. Each slip plane is assumed to contain active sources of dislocations leading to a constant density of non-interacting dislocations in the plane which glide through randomly distributed localized point obstacles, representing small precipitates. The dislocation is assumed to have a constant line tension and the dislocation-obstacle interaction is taken to have a simple step form. Using results of computer simulation of thermally activated glide through random arrays of point obstacles, deformation was modeled as a function of temperature and applied stress, determining the strain rate and the morphological characteristics of slip.
