Statistics of slip avalanches in sheared amorphous materials based on atomistic simulation
… have found that amorphous materials deform via slip avalanches in the plastic regime, which are bursts of plastic flows and show scale free features, as evidenced by a power-law probability distribution of the magnitude of serrations in stress-strain curves. Mesoscale models of amorphous …

Temporal properties of avalanche dynamics
Slip avalanches occur in both crystalline and amorphous solids. Slip avalanches and avalanches in other systems are thought to be critical phenomena linked to a nonequilibrium phase transition. In this thesis we explore some temporal properties of experimental slip avalanche dynamics. These …

Plasticity as a depinning phase transition
… materials deform in an intermittent way with slip-avalanches that are power-law distributed. In this work we study plasticity as a pinning-depinning phase transition employing a discrete dislocation dynamics (DDD) model and a phase eld crystal (PFC) model in two dimensions. Below a critical ( …
