A Statistical Connection Between Dislocations and Mechanical Properties



Lyle E. Levine, R M. Thomson


The extreme complexity of the dislocation-based processes that underlie plastic deformation are in marked contrast to the relatively simple behavior observed macroscopically. The simplification arises because a deforming metal can be described as a self-organizing critical system, where the internal state variables are statistical dislocation-transport parameters. The connection to dislocation and lower-level atomistic processes comes in through the continuously evolving distribution of dislocation segment lengths within the dislocation cell walls.
