Micromechanics-based stress-dilatancy relationship for granular materials
Yantu gongcheng xuebao, 2021 From the perspective of micromechanics, the formulas for the average contact force and contact displacement in the granular are derived based on the true stress tensor, then the stress-shear dilatancy relationship considering the fabric anisotropy and ...

Viscoelasticity of granular materials
Mechanics of Materials, 1995 Abstract In a former work (V.T. Granik and M. Ferrari (1993), Microstructural mechanics of granular media, Mech. Mater. 15, 301–322) a micromechanical theory for elastic granular media was deduced on the basis of the identification of the constituent grains with the nodes of a Bravais lattice.

Transport Properties and Segregation Phenomena in Vibrating Granular Beds
KONA Powder and Particle Journal, 2016 Granular materials are common in daily life and in many industrial processes. Both fundamental research and industrial application studies are crucial for understanding the transport properties and segregation mechanisms of vibrating granular beds.

The variation of grain size distribution in rock granular material in seepage process considering the mechanical–hydrological–chemical coupling effect: an experimental research [PDF]
Royal Society Open Science, 2020 As a common solid waste in geotechnical engineering, rock granular material should be properly treated and recycled. Rock granular material often coexists with water when it is used as the filling material in geotechnical engineering.

Scaling properties of granular materials [PDF]
Physical Review E, 2001 Given an assembly of viscoelastic spheres with certain material properties, we raise the question how the macroscopic properties of the assembly will change if all lengths of the system, i.e. radii, container size etc., are scaled by a constant. The result leads to a method to scale down experiments to lab-size.

Mixing Fluids and Granular Materials [PDF]
Computer Graphics Forum, 2009 AbstractFluid animations in computer graphics show interactions with various kinds of objects. However, fluid flowing through a granular material such as sand is still not possible within current frameworks. In this paper, we present the simulation of fine granular materials interacting with fluids.

Creep response of granular materials [PDF]
EPJ Web of ConferencesWe present an experimental study of creep deformation measured in a dry granular material submitted to a constant deviatoric stress smaller than its failure threshold. We observe creep deformation leading to material failure. An interferometric method of

Quasistatic response of loose cohesive granular materials [PDF]
EPJ Web of Conferences, 2021 DEM-simulated model cohesive assemblies of spherical grains of diameter d, with contact tensile strength F0, once prepared in loose states, are quasistatically subjected to growing isotropic pressure P, and then to triaxial compression, maintaining ...

Theory of shear strength of granular materials based on particle breakage
Yantu gongcheng xuebao, 2018 Great efforts have been made to determine the shear strength of coarse granular materials using both elaborate laboratory tests and empirical methods. However, the elaborate laboratory tests are difficult and time consuming to perform, and the physical ...
