Depth and slip ratio dependencies of friction for a sphere rolling on a granular slope
Takeshi Fukumoto, Hiroyuki Ebata, Ishan Sharma +1
We experimentally investigate the dynamics of a sphere rolling down a granular slope by varying the initial velocity, slope angle, and sphere density. The results show that the sph…
Axisymmetric landslides on small planetary bodies
Kumar Gaurav, Ishan Sharma
We aim to understand how landslides affect the shape and rotational motion of small rubble planetary bodies. We limit ourselves to axisymmetric global landslides, and take the prim…
Coupled shape and spin evolution of small near spherical asteroids due to global regolith motion
Kumar Gaurav, Deepayan Banik, Ishan Sharma
Recent space missions have provided substantial evidence of regolith movement on the surfaces of near Earth asteroids. To investigate this phenomenon, we present a continuum-based…
Granular flows over normally vibrated inclined bases
Prasad Sonar, Ashish Bhateja, Ishan Sharma
We investigate granular flows over an inclined rigid base, which is vibrated externally in a direction normal to itself, through discrete element simulations. We vary the base incl…
Segregation on small rubble bodies due to impact-induced seismic shaking
Sohanjit Ghosh, Ishan Sharma, Deepak Dhingra
We present a framework to study regolith segregation on rubble-pile asteroids (self-gravitating granular aggregates) due to seismic shaking induced by impacts sustained during thei…
