This survey provides an overview of the different approaches seen in the literature
concerning particle damping. The emphasis is on particle dampers used on beams vibrating …

Granular materials are comprised of solid, athermal grains. Whilst immune to thermal
motion, these grains move and diffuse when they undergo shear deformation. Here we …

The packing and flow of aspherical frictional particles are studied using discrete element
simulations. Particles are superballs with shape| x| s+| y| s+| z| s= 1 that varies from sphere …

Understanding and predicting dense granular flows is of importance in geology and
industrial applications. Still, most theoretical work has been limited to flows and packings …

The particle damper (PD) filled with granular material exhibits hysteretic behavior under
dynamic excitation, meaning that its response depends not only on the current excitation but …

The macroscopic friction of particulate materials often weakens as the flow rate is increased,
leading to potentially disastrous intermittent phenomena including earthquakes and …

We use numerical simulations to study the effect of particle friction on suspension flows of
non-Brownian hard particles. By systematically varying the microscopic friction coefficient μ …

Pressure-imposed rheometry is used to examine the influence of surface roughness on the
rheology of immersed and dry frictional spheres in the dense regime. The quasistatic value …

We study the microscopic origin of nonlocality in dense granular media. Discrete element
simulations reveal that macroscopic shear results from a balance between microscopic …

Understanding the rheology of granular assemblies is important for natural and engineering
systems, but the relationship between inter-particle friction (or microscopic friction) and …
