Granular materials in geotechnical engineering is generally considered to be mixtures of clay, sand, and gravel that commonly appear in slopes, valleys, or river beds, and they are especially used for the construction of earth-rock-filled dams.

Jamming for a 2D granular material [PDF]
This paper focuses on the nature of jamming, as seen in two-dimensional frictional granular systems consisting of photoelastic particles. The photoelastic technique is unique at this time, in its capability to provide detailed particle-scale information on forces and kinematic quantities such as particle displacements and rotations.

Coupling between rotational and translational motions of a vibrated polygonal disk
We investigate experimentally the dynamics of a single polygonal disk (regular n -gon with 3 ⩽ n ⩽ 8) confined in a closed container under vertical vibrations against gravity.

Micromechanics of Liquefaction in Granular Materials [PDF]
A discrete element method (DEM) implementation is developed to study the micromechanics of liquefaction in granular materials. In a liquefaction event, the pore water acts as a cushion between the grains, reducing the contact and friction forces and the overall soil strength.

Microstructural anisotropy as the origin of dilatancy [PDF]
Dilation in sheared granular materials has been widely observed, yet its micromechanical origins remain debated. Using discrete element method (DEM) simulations of slow granular flows, we find that grain rearrangements occur intermittently, alternating ...

ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Numerical simulation of cementitious granular materials
A new numerical approach was developed to study the mechanical properties of cementitious granular materials. At first, an ellipsoid based method was developed to generate aggregate particles of arbitrary shape.
