Evaluating the repose angle of granular materials under different kinds of gravitational conditions is essential for in situ resource exploration on surfaces of other Earth-like planets in the next decades. The forming process of particulate pile under different kinds of gravitational accelerations was simulated by three-dimensional discrete element method (DEM). where the particulate... https://www.roneverhart.com/Heel-Elbow-Protectors-Premium-Heel-Elbow-Protector-Blue-Medium-Pair-66053/
