Impacts and Ejecta in Natural Granular Material
Esteban Wright, Emau Argueta, Wolfgang Losert
With laboratory experiments we investigate the ejecta of low-velocity (~m/s) impacts into multi-scale granular media and compare them against ejecta from impacts into mono-scale me…
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…
Froude number scaling unifies impact trajectories into granular media across gravitational conditions
Peter M. Miklavcic, Ethan Tokar, Esteban Wright +4
The interactions of solid objects with granular media is countered by a resistance force that stems from frictional forces between the grains and the media's resistance to inertia…
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…
