Twisting, an alternative strategy to compact granular materials
EPJ Web of Conferences, 2017 Nowadays, the common method to pack granular materials is to tap the ensemble against the gravity. Despite the apparent simplicity of that method, the asymptotic states reached by the tapped systems have strongly dependences on parameters like the shape ...

Real‐Time Remodeling of Granular Terrain for Robot Locomotion
Advanced Intelligent Systems, 2022 Terrain irregularities in natural environments present mobility challenges for autonomous robots and vehicles. Loosely consolidated sandy slopes flow unpredictably when perturbed, often leading to locomotion failure.

Hysteresis in vibrated granular media [PDF]
, 2000 Some general dynamical properties of models for compaction of granular media based on master equations are analyzed. In particular, a one-dimensional lattice model with short-ranged dynamical constraints is considered.

Vertical drag force acting on intruders of different shapes in granular media
EPJ Web of Conferences, 2017 The penetration of large objects into granular media is encountered commonly both in nature (e.g. impacts of meteors and projectiles) and engineering applications (e.g. insertion of tractor blades into sand).

Granular Resistive Force Theory Extension for Saturated Wet Sand Ground
Machines, 2022 Amphibious environments formed from sand and water present a formidable challenge to the running motion of field robots, as the mixing of granular media (GM) and water makes the force laws of robotic legs more complicated during robot running.

Why granular media are thermal after all
EPJ Web of Conferences, 2017 Two approaches exist to account for granular behavior. The thermal one considers the total entropy, which includes microscopic degrees of freedom such as phonons; the athermal one (as with the Edward entropy) takes grains as elementary.

Analytical method for stress of granular medium foundation under vertical load
Yantu gongcheng xuebao, 2017 The analytical method for stress of foundation under vertical load is an important basis of design and computation in foundation engineering. However, the existing methods cannot reflect the properties of granular media for foundation soils.
