Sand production, a challenge in the geo-energy industry, compromises reservoir integrity
and equipment by eroding and transporting sand grains from unconsolidated and weakly …

The central collision between two solid spheres or the normal collision between a sphere
and a plate are important to understand in detail before studying more complex particle …

The coefficient of restitution e is determined as the ratio of the final to the initial relative
velocity between two moving objects after their collision. It is also one of the basic features …

A Soft-Sphere Discrete Element Method (SSDEM) is used to simulate the rotational
reshaping and disruption of cohesionless self-gravitating granular aggregates (as a …

Recent advances in fluvial seismology have provided solid observational and theoretical
evidence that near‐river seismic ground motion may be used to monitor and quantify coarse …

The 1963 Vajont rock slide is studied using the distinct-element method (DEM). Two-
dimensional (2D) and three-dimensional (3D) DEM models were constructed based on …

Measuring the strengths of asteroidal materials is important for developing mitigation
strategies for potential Earth impactors and for understanding properties of in situ materials …

Aims. We investigate the possibility that the observed sea-otter shape of the asteroid
Itokawa, associated with the presence of big boulders on its surface, originates from the …

Quantifying debris‐flow characteristics remains a key challenge in natural hazard research.
Recent studies suggest that seismic signals can reveal debris‐flow properties. However, the …

Packed beds are used for solar power energy storage, in the chemical and process
industries, and in nuclear reactors. Mining ventilation coolth is the application of interest …
