In this work, modeling of the stress–strain behavior is carried out using a simple dislocation model. This model uses three variables to characterize the dislocation population: The average forest and mobile dislocation densities, ρf and ρm, and

A method for the construction of “processing windows” to avoid negative strain-rate sensitivity and associated serrated flow in some aluminum alloys is described. The method is based on modern approaches and techniques of non-linear dynamics –

Phase modulations of periodic dislocation patterns observed in transmission electron microscopy (TEM) studies of some single crystalline metals, are analyzed using the methods of nonlinear dynamics. The Ginzburg–Landau (GL) equation for the soft mo

The machine equation plays an important role in the analysis of experimental data on mechanical testing and in modeling work. Its careful derivation has been provided both for the case of infinitesimally small deformations (brief recapitulation of th

The existing models for the “classical” Portevin-Le-Chatelier effect have been analyzed, and the non-linear dynamical model has been proposed in order to quantify the nature of temporal instabilities in fatigued metallic alloys. The model employs

An attempt to employ the self-organization theory has been made in order to describe different types of dislocation patterning in fatigued metals. We demonstrate that the formation of certain patterns can be understood as a result of competition betw

It is shown that in certain materials plastic instabilities of different types may be traced back to the same physical mechanism. Depending on experimental conditions, transitions between various types of instability may take place, i.e., the classif
