We investigate the motion of groups of intruders in a two-dimensional granular system by
using discrete numerical simulations. By imposing either a constant velocity or a thrusting …

Soft materials often display complex behaviors that transition through apparent solid-and
fluid-like regimes. While a growing number of microscale simulation methods exist for these …

The intrusion of deformable compound anchors in dry sand is simulated by coupling the
Finite Element Method (FEM) with Smoothed Particle Hydrodynamics (SPH). This novel …

We examine the drag experienced by a pair of vertical rods moving in tandem through a
granular bed immersed in a fluid as a function of their separation distance and speed. As in …

The morphology-performance-fitness paradigm has long been a guiding principle inspiring
a great deal of laboratory and field studies fundamental to understanding functional …

In many industrial or geotechnical applications, objects move through a granular medium
and an important issue is the prediction of the force that develops during the motion of the …

When several intruders move in a granular medium, coupling effects are observed, the
motion of one intruder affecting that of others. In this paper, we investigate experimentally …

We studied the formation of doublet craters generated by binary projectiles (steel beads or
granular agglomerates) impacting simultaneously at low speed against a sand bed. For …

Granular intrusions such as ballistic impacts, vehicular and animal locomotion in natural
terrains, and stirring of materials in industrial processes are common. Granular media often …

Intrusions into granular media are common in natural and engineered settings (eg during
animal locomotion and planetary landings). While intrusion of complex shapes in dry non …
