Predicting the morphodynamics of sedimentary landscapes due to fluvial and aeolian flows
requires answering the following questions: Is the flow strong enough to initiate sediment …

The formation of cracks and emergence of shearing planes and other modes of rapid
macroscopic failure in geologic granular media involve numerous grain scale mechanical …

The macroscopic friction of particulate materials often weakens as the flow rate is increased,
leading to potentially disastrous intermittent phenomena including earthquakes and …

Quantifying the effect of external forcings like seismicity or rain on slope destabilization is a
long-standing and challenging issue. To investigate the respective roles of these forcings …

In mountainous terrain, large earthquakes often cause widespread coseismic landsliding as
well as hydrological and hydrogeological disturbances. A subsequent transient phase with …

Understanding the dynamic response of granular shear zones under cyclic loading is
fundamental to elucidating the mechanisms triggering earthquake-induced landslides, with …

A fundamental mystery in earthquake physics is “how can an earthquake be triggered by
distant seismic sources?” Here we use discrete element method simulations of a granular …

We describe an experiment container with light scattering and imaging diagnostics for
experiments on soft matter aboard the International Space Station (ISS). The suite of …

This paper reports results of a three-dimensional discrete element method modeling
investigation of the role of boundary vibration in perturbing stick-slip dynamics in a sheared …

This study investigated the effects of sound wave magnitude on the sound absorption
characteristics of granular materials. The normal incidence sound absorption coefficients of …
