On the kinetics of localized plasticity domains emergent at the pre-failure stage of deformation process
چکیده انگلیسی

The behavior of localized plasticity domains occurring at the final stage of plastic flow process has been investigated. A series of runs was conducted on materials differing in crystal lattice type, which enabled establishment of the regular features exhibited by the flow process upon a transition to macroscopic necking and viscous failure. It is found that the most distinctive regularity is the occurrence of flow domains, which are moving in a concerted manner towards the pole of a bundle of domain trajectories plotted in the time–space co-ordinates. The deformation patterns are found to be related to the kinetics of nucleation and motion of localized plasticity fronts. The probable origin of the observed effects is considered.
