Avalanche dynamics are found in many phenomena, from earthquakes to the evolution of
species. They can also be found in vortex matter when a type-II superconductor is externally …

Plastic deformation is a highly dissipative process that induces a variety of patterns such as
the cell structure in multislip conditions, the matrix structure and the persistent slip bands in …

We simulate the glide motion of an assembly of interacting dislocations under the action of
an external shear stress and show that the associated plastic creep relaxation follows …

The collective behavior of dislocations in jerky flow is studied in Al-Mg polycrystalline
samples subjected to constant strain rate tests. Complementary dynamical, statistical, and …

Recent observations of jerky flow in high-entropy alloys (HEA) revealed a high role of self-
organization of dislocations in their plasticity. The present work reports the first results of the …

In this study, the effect of a Cu/Ni bilayered coating on the shear banding behavior and
compressive plasticity of a Zr-based bulk metallic glass (BMG) was investigated. As …

The unstable plastic flow of an AlMg alloy, associated with the Portevin-Le Chatelier effect,
was studied near the lower strain-rate boundary of instability using multifractal analysis. Self …

The analysis of experimental time series, obtained from single and polycrystals subjected to
constant strain rate tests, reports an intriguing dynamical crossover from a low-dimensional …

Using molecular dynamics simulation, we examine the dynamics of crystal, polycrystal, and
glass in a Lennard-Jones binary mixture composed of small and large particles in two …
