Subsurface pulse, crater and ejecta asymmetry from oblique impacts into granular media
Bingcheng Suo, A. C. Quillen, Max Neiderbach +9
We carry out experiments of 104 m/s velocity oblique impacts into a granular medium (sand). Impact craters have nearly round rims even at a grazing angle of about , howev…
Surface particle motions excited by a low velocity normal impact into a granular medium
Max Neiderbach, Bingcheng Suo, Esteban Wright +5
In laboratory experiments, high speed videos are used to detect and track mm-size surface particle motions caused by a low velocity normal impact into sand. Outside the final crate…
Sub-surface granular dynamics in the context of oblique, low-velocity impacts into angular granular media
Peter M. Miklavčič, Hesam Askari, Paul Sánchez +2
Oblique, low-velocity impacts onto extraterrestrial terrain are an inevitable occurrence during space exploration. We conduct two-dimensional discrete simulations to model such imp…
Propagation and attenuation of pulses driven by low velocity normal impacts in granular media
A. C. Quillen, Max Neiderbach, Bingcheng Suo +7
We carry out experiments of low velocity normal impacts into granular materials that fill an approximately cylindrical 42 litre tub. Motions in the granular medium are tracked with…
Ricochets on Asteroids II: Sensitivity of laboratory experiments of low velocity grazing impacts on substrate grain size
Esteban Wright, Alice C. Quillen, Paul Sanchez +4
We compare low velocity impacts that ricochet with the same impact velocity and impact angle into granular media with similar bulk density, porosity and friction coefficient but di…
Accretion of Ornamental Equatorial Ridges on Pan, Atlas and Daphnis
Alice C. Quillen, Fatima Zaidouni, Miki Nakajima +1
We explore scenarios for the accretion of ornamental ridges on Saturn's moons Pan, Atlas, and Daphnis from material in Saturn's rings. Accretion of complex shaped ridges from ring…
