A debris flow represents a mixture of sediment particles of various sizes and water flowing
down a confined, channel-shaped region (eg, gully, ravine or valley) down to its end, at …

This article reviews the behavior of materials made up of a large assemblage of solid
particles under rapid and quasi static deformations. The focus is on flows at relatively high …

Many geotechnical problems are conditioned by the coupling effects between the solid
matrix and fluid transport, in particular in unsaturated zones: construction of embankments …

In the mechanics of multiphase (or multicomponent) mixtures, one of the outstanding issues
is the formulation of constitutive relations for the interaction force. In this paper, we give a …

We study steady, fully developed, axisymmetric flows of soft, inelastic grains within a vertical
circular pipe under the influence of gravity. We use extended kinetic theory to describe the …

In this paper, we discuss the importance of constitutive modeling of the stress tensors in
certain engineering issues, related to the pressure drop and skin friction, encountered in …

In this paper we will explore the consequences of the Mohr-Coulomb criterion on the
constitutive equation proposed by Rajagopal and Massoudi [1]. This contunuum model …

A granular material is a collection of a large number of discrete solid particles with interstices
filled with a fluid or a gas. If the interstitial fluid plays an insignificant role in the transportation …

Using a mathematical description for a flowing mixture of solid particulates developed
previously within the context of Mixture Theory, the equations governing the flow of a two …

Based on ideas proposed by Massoudi and Rajagopal (M‐R), we develop a model for blood
using the theory of interacting continua, that is, the mixture theory. We first provide a brief …
