Crossover from quasi-static to dense flow regime in compressed frictional granular media

Florent Gimbert, David Amitrano, Jérôme Weiss

We investigate the evolution of multi-scale mechanical properties towards the macroscopic mechanical instability in frictional granular media under multiaxial compressive loading.…

Intermittent dislocation flow in viscoplastic deformation

M. -Carmen Miguel, Alessandro Vespignani, Stefano Zapperi +2

The viscoplastic deformation (creep) of crystalline materials under constant stress involves the motion of a large number of interacting dislocations. Analytical methods and sophis…

Complexity in dislocation dynamics: model

M. -Carmen Miguel, Alessandro Vespignani, Stefano Zapperi +2

We propose a numerical model to study the viscoplastic deformation of ice single crystals. We consider long-range elastic interactions among dislocations, the possibility of mutual…
