Compression of anisometric granular materials
Powder Technology, 2019Abstract Granular particles of anisometric shape are common in many technologies and the knowledge of their compression response is needed for their handling, storage, transport and flow. Despite its importance, a little attention has been paid to this problem so far.

Abstract : The research under this contract has been directed mainly toward the understanding of the optical behavior of those composite materials whose components are separated on a scale that is very small ( 100 A) compared with the wavelength of light.

BEYOND FAILURE IN GRANULAR MATERIALS
International Journal for Numerical and Analytical Methods in Geomechanics, 1997The interrelations among different constitutive models of granular materials are discussed with special reference to failure and stability. For the hyperplastic constitutive equation, the accessible stress states and the stable stress states are found to be enclosed by a bound surface and a stability surface in the stress space, respectively ...

Averaging method of granular materials
Physical Review E, 2002This paper presents an averaging method to link discrete to continuum variables of granular materials. Compared to the other methods proposed in the literature, it has advantages of being applicable to all flow regimes, and to granular flows with or without the effect of physical boundaries.

A distinguishing feature between flows of granular materials and other solidfluid mixtures is that in granular flows the direct interaction of particles leads to energy dissipation which plays an important role in the flow mechanics. For example, take a pebble and drop it onto the sand on a beach.

Elastoplastic Waves in Granular Materials
Journal of Applied Mechanics and Technical Physics, 2003For a description of the deformation of materials with different resistances to tension and compression, the conventional rheological diagram is supplemented by a new element --- rigid contact. It is used to construct a model of an ideal granular material possessing elastic and plastic properties.

Micromechanical Modeling of Granular Materials
2002We briefly review attempts to predict the mechanical response of granular materials based on a simple characterization of the interparticle force and the statistical geometry of their packing and interactions. The results of two such theories are presented.

Axial segregation of granular materials
Chaos: An Interdisciplinary Journal of Nonlinear Science, 1999When mixtures of granular materials are rotated, it is often found that they segregate into bands, along the axis of rotation, which are rich in the various components. This effect is discussed experimentally and theoretically, with emphasis on a mechanism based on surface flow.
