Negative Strain-Rate Sensitivity in Metallic Glasses Driven by Rejuvenation-Relaxation Competition: Kinetic Monte Carlo Simulations and a Minimal Effective Model
Tomoaki Niiyama, Akio Ishii, Takahiro Hatano +2
When strain-rate sensitivity (SRS) is negative in metallic glasses, the material becomes weaker as the deformation rate increases, leading to accelerated plastic deformation and, e…
Inter-event time statistics of earthquakes as a gauge of volcano activity
Sumanta Kundu, Anca Opris, Yosuke Aoki +1
The probability distribution of inter-event time (IET) between two consecutive earthquakes is a measure for the uncertainty in the occurrence time of earthquakes in a region of int…
Earthquake magnitude distribution and aftershocks: a statistical geometry explanation
François Pétrélis, Kristel Chanard, Alexandre Schubnel +1
The emergence of a power-law distribution for the energy released during an earthquake is investigated in several models. Generic features are identified which are based on the sel…
Modeling crack propagation in heterogeneous materials: Griffith's law, intrinsic crack resistance and avalanches
Subhadeep Roy, Takahiro Hatano, Purusattam Ray
Various kinds of heterogeneity in solids including atomistic discreteness affect the fracture strength as well as the failure dynamics remarkably. Here we study the effects of an i…
Slow periodic oscillation without radiation damping: New evolution laws for rate and state friction
Ryo Mizushima, Takahiro Hatano
The dynamics of sliding friction is mainly governed by the frictional force. Previous studies have shown that the laboratory-scale friction is well described by an empirical law st…
Model for creep failure with healing
Subhadeep Roy, Takahiro Hatano
To understand the general properties of creep failure with healing effects, we study a mean-field fiber bundle model with probabilistic rupture and rejoining processes. The dynamic…
