The slip-rate, state-, temperature-, and normal-stress-dependence of fault frictionKey points
Earthquake ScienceThe mechanics of slow-slip events and earthquakes is controlled by the constitutive behavior of rocks in active fault zones, which is sensitive to many factors encompassing lithology, temperature, confining and pore-fluid pressure, and slip-rate, among ...

The role of radiation damping in the modeling of repeated earthquake events
Annals of Geophysics, 2013 We have investigated the role of the radiation damping term (RDT) on repeated earthquake ruptures by modeling the faulting process through a single one-dimensional analog fault system governed by different constitutive laws.

Dense granular flows: two-particle argument accounts for friction-like constitutive law with threshold [PDF]
, 2008 A scalar constitutive law is obtained for dense granular flows, both in the inertial regime where the grain inertia dominates, and in the viscous regime.

Advanced Functional Materials, EarlyView.The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

Transient and Steady‐State Friction in Non‐Isobaric Conditions
Geochemistry, Geophysics, GeosystemsThe frictional properties of faults control the initiation and propagation of earthquakes and the associated hazards. Although the ambient temperature and instantaneous slip velocity controls on friction in isobaric conditions are increasingly well ...

Simulation of the small punch creep test with consideration of variation of material properties [PDF]
, 2009 A new finite element model of the small punch creep test is described. The material constitutive relationship for creep considered is a simple Norton power law: in this study the exponent in the power law is varied for each element to simulate the random
