Forces on an intruder combining translation and rotation in granular media

Abstract

Using two-dimensional numerical simulations, we study the set of mechanical actions (drag, lift and torque) exerted by a granular medium on a cross-shaped object buried within it. The object has the ability to translate horizontally and rotate at independent imposed velocities. We show that the simulation results are consistent with the Granular Resistive Force Theory often applied in granular locomotion problems.
