Abstract:

Past developments of the micro-dynamical description of plastic flow are outlined, and the successes of the theory are mentioned. Then some extensions in scope are suggested and discussed. These include application to polymeric solids, collective dislocation behavior, and dynamics of precipitation hardening. The difficulty that the flowing-state differs from the post-flowing-state is emphasized. It is proposed that dislocation lines exist in noncrystalline solids and provide a convenient description for local shear correlations. The possibility that flutter is induced in moving dislocations by turbulent phonon-gas flow is considered. Finally, an atomic model for dislocation mobility in covalent crystals is presented. Author
