Journal ArticleDOI
A constitutive model for wet granular materials
TL;DR: In this article, the authors show that over a certain range of shear rate levels, both the shear stress and the normal stress that develop are linear in the number of shears.
Journal ArticleDOI
Inhomogeneous non-unidirectional deformations of an elastic wedge
Journal ArticleDOI
Implicit type constitutive relations for elastic solids and their use in the development of mathematical models for viscoelastic fluids
TL;DR: In this article, the Gibbs free energy instead of the Helmholtz free energy is used to model the left Cauchy-Green tensor as a function of stress in the context of viscoelastic fluids.
Journal ArticleDOI
Special Cosserat rods with rate-dependent evolving natural configurations
TL;DR: In this paper , a nonlinear, geometrically exact, and thermodynamically consistent framework for modeling special Cosserat rods with evolving natural configurations is presented. But unlike the point-wise Clausius-Duhem inequality, the strictly weaker form that the rate of total entropy production is non-decreasing.
Journal ArticleDOI
Flow reversals of a non-Newtonian fluid in an expanding channel
TL;DR: In this article , the authors consider the flow of an incompressible power-law fluid through convergent-divergent channels, where the choice of the viscosity is such that the zero-shear rate viscosities is neither zero nor infinity for any finite value of the power law exponent.
