Undulatory forcing of an intruder through granular media: effects of frequency and packing fraction
Douglas Daniel de Carvalho, Erick de Moraes Franklin
We investigate the motion amid grains of an intruder undergoing an imposed force that oscillates with a given frequency. For that, we made use of discrete numerical simulations whe…
Cratering by the oblique impact of a spinning projectile
Douglas Daniel de Carvalho, Erick de Moraes Franklin
We investigate the roles of spin and packing fraction on the dynamics of cratering when a solid projectile impacts a granular bed at different incident angles. For that, we carried…
Impact craters formed by spinning granular projectiles
Douglas Daniel de Carvalho, Nicolao Cerqueira Lima, Erick de Moraes Franklin
Craters formed by the impact of agglomerated materials are commonly observed in nature, such as asteroids colliding with planets and moons. In this paper, we investigate how the pr…
Roles of packing fraction, microscopic friction and projectile spin in cratering by impact
Douglas Daniel de Carvalho, Nicolao Cerqueira Lima, Erick de Moraes Franklin
From small seeds falling from trees to asteroids colliding with planets and moons, the impact of projectiles onto granular targets occurs in nature at different scales. In this pap…
Collaborative behavior of intruders moving amid grains
Douglas Daniel de Carvalho, Erick de Moraes Franklin
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…
Contacts, motion and chain-breaking in a two-dimensional granular system displaced by an intruder
Douglas Daniel de Carvalho, Nicolao Cerqueira Lima, Erick de Moraes Franklin
We investigate numerically how the motion of an intruder within a two-dimensional granular system affects its structure and produces drag on the intruder. We made use of discrete n…
