Stick-slip instabilities in sheared granular flow: the role of friction and acoustic vibrations
Charles K. C. Lieou, Ahmed E. Elbanna, J. S. Langer +1
We propose a theory of shear flow in dense granular materials. A key ingredient of the theory is an effective temperature that determines how the material responds to external driv…
Shear flow of angular grains: acoustic effects and non-monotonic rate dependence of volume
Charles K. C. Lieou, Ahmed E. Elbanna, J. S. Langer +1
Naturally-occurring granular materials often consist of angular particles whose shape and frictional characteristics may have important implications on macroscopic flow rheology. I…
A two-scale model for sheared fault gouge: Competition between macroscopic disorder and local viscoplasticity
Ahmed E. Elbanna, Jean M. Carlson
We develop a model for sheared gouge layers that accounts for the local increase in temperature at the grain contacts during sliding. We use the shear transformation zone (STZ) the…
Rate dependent shear bands in a shear transformation zone model of amorphous solids
M. L. Manning, E. G. Daub, J. S. Langer +1
We use Shear Transformation Zone (STZ) theory to develop a deformation map for amorphous solids as a function of the imposed shear rate and initial material preparation. The STZ fo…
Shear strain localization in elastodynamic rupture simulations
Eric G. Daub, M. Lisa Manning, Jean M. Carlson
We study strain localization as an enhanced velocity weakening mechanism on earthquake faults. Fault friction is modeled using Shear Transformation Zone (STZ) Theory, a microscopic…
Strain localization in a shear transformation zone model for amorphous solids
M. L. Manning, J. S. Langer, J. M. Carlson
We model a sheared disordered solid using the theory of Shear Transformation Zones (STZs). In this mean-field continuum model the density of zones is governed by an effective tempe…
