Granular flow experiment using artificial gravity generator at International Space Station
npj Microgravity, 2023 Studying the gravity-dependent characteristics of regolith, fine-grained granular media covering extra-terrestrial bodies is essential for the reliable design and analysis of landers and rovers for space exploration.

Force Transmission in Granular Media
KONA Powder and Particle Journal, 2014 Powders and other granular media are composed of discrete particles and force transmission through a system of particles can only occur via the interparticle contacts. The distribution of contact orientations affects

Efficient reciprocating burrowing with anisotropic origami feet
Frontiers in Robotics and AI, 2023 Origami folding is an ancient art which holds promise for creating compliant and adaptable mechanisms, but has yet to be extensively studied for granular environments.

Dynamic Effective Mass of Granular Media [PDF]
Physical Review Letters, 2009 We develop the concept of frequency dependent effective mass, M(omega), of jammed granular materials which occupy a rigid cavity to a filling fraction of 48%, the remaining volume being air of normal room condition or controlled humidity. The dominant features of M(omega) provide signatures of the dissipation of acoustic modes, elasticity and aging ...

Modeling of the interaction of rigid wheels with dry granular media
, 2019 We analyze the capabilities of various recently developed techniques, namely Resistive Force Theory (RFT) and continuum plasticity implemented with the Material Point Method (MPM), in capturing dynamics of wheel--dry granular media interactions.

Plug flow and the breakdown of Bagnold scaling in cohesive granular flows
, 2005 Cohesive granular media flowing down an inclined plane are studied by discrete element simulations. Previous work on cohesionless granular media demonstrated that within the steady flow regime where gravitational energy is balanced by dissipation arising

Collision Rates in Charged Granular Gases [PDF]
, 2002 The dissipation rate due to inelastic collisions between equally charged, insulating particles in a granular gas is calculated. It is equal to the known dissipation rate for uncharged granular media multiplied by a Boltzmann-like factor, that originates ...
