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.

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.

Granular Crystals: Controlling Mechanical Energy with Nonlinearity and Discreteness [PDF]
, 2011 The presence of structural discreteness and periodicity can affect the propagation of phonons, sound, and other mechanical waves. A fundamental property of many of the periodic structures and materials designed for this purpose is the presence of ...

Calculation of multilayer sieve classifiers for separating grained materials by size [PDF]
E3S Web of Conferences, 2021 From the standpoint of stochastic Poisson processes, the separation of granular materials by size on multi-tiered sieve classifiers is studied. Taking into account the selected separation scheme, a system of stochastic differential equations is drawn up ...

On the Failure of the Granular Material
Soils and Foundations, 1967 SYNOPSIS Notwithstanding the statistical theory of mechanics of granular material proposed by the senior author, was established basing on experimental evidences, still it contained several uncertain assumptions. By the bi-axial compression tests on assemblage of equal balls, almost all of assumptions were ascertained. Observing the failure phenomena,

Granular Material Development Applied in an Experimental Section for Civil Engineering Purposes
Applied Sciences, 2020 In this study, a granular material (GM) derived from wastes generated in waste-to-energy plants was developed. Weathered bottom ash (WBA) and air pollution control (APC) ashes obtained from municipal solid waste incineration (MSWI) were used as raw ...
