Impact on granular beds

D Van Der Meer - Annual review of fluid mechanics, 2017 - annualreviews.org
The impact of an object on a granular solid is an ubiquitous phenomenon in nature, the
scale of which ranges from the impact of a raindrop onto sand all the way to that of a large …

Archimedes' law explains penetration of solids into granular media

W Kang, Y Feng, C Liu, R Blumenfeld - Nature communications, 2018 - nature.com
Understanding the response of granular matter to intrusion of solid objects is key to
modelling many aspects of behaviour of granular matter, including plastic flow. Here we …

[HTML][HTML] The effectiveness of resistive force theory in granular locomotion

T Zhang, DI Goldman - Physics of Fluids, 2014 - pubs.aip.org
Resistive force theory (RFT) is often used to analyze the movement of microscopic

Collisional model for granular impact dynamics

AH Clark, AJ Petersen, RP Behringer - Physical review E, 2014 - APS
When an intruder strikes a granular material from above, the grains exert a stopping force
which decelerates and stops the intruder. Many previous studies have used a macroscopic …

Macroscopic force experienced by extended objects in granular flows over a very broad Froude-number range: macroscopic granular force on extended object

T Faug - The European Physical Journal E, 2015 - Springer
This paper revisits a great number of data from previous studies about the macroscopic force
experienced by either objects moving at constant speed and depth inside static granular …

Settling into dry granular media in different gravities

E Altshuler, H Torres, A González‐Pita… - Geophysical …, 2014 - Wiley Online Library
While the penetration of objects into granular media is well‐studied, there is little
understanding of how objects settle in gravities, geff, different from that of Earth—a scenario …
