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.
