Rolling Dynamics of a Cylinder

This lecture covers the rolling dynamics of a cylinder containing granules, investigating its behavior when rolling down an inclined plane. The critical angle for rolling, the sliding angle of granules, and the oscillation frequency of the system are discussed. The lecture also explores the dissipation of energy in the system based on volume and mass fractions. Various theoretical, experimental, and simulation studies on granular motion inside containers are referenced, with a focus on the dynamics of non-rigid objects. The presentation delves into the challenges posed by inhomogeneous mass density and the dynamics of containers filled with fluids or granules.
