Journal ArticleDOI
Secondary Deformations Due to Axial Shearing of the Annular Region Between Two Eccentrically Placed Cylinders
TL;DR: In this article, it was shown that if on the other hand the driving force is not small (of O(1)), but the departure of the cylinder from circular symmetry is small, then secondary deformations appear at first order, the parameter for perturbance being the divergence from the circular symmetry.
Journal ArticleDOI
The State of Stress and Strain Adjacent to Notches in a New Class of Nonlinear Elastic Bodies
TL;DR: In this paper, the deformation of a body with a smoothened V-notch subject to an anti-plane state of stress was studied in the context of a new class of elastic models.
Journal ArticleDOI
Non-homogeneous deformations in a wedge of Mooney-Rivlin material
TL;DR: In this article, the authors studied the non-homogeneous deformation of a wedge of Mooney-Rivlin material and found that the deformation is neither purely inward nor purely outward, but a combination of the two.
Journal ArticleDOI
Discretization of an unsteady flow through a porous solid modeled by darcy's equations
TL;DR: In this paper, a discretization of the Darcy's equations is proposed to model the time-dependent flow of an incompressible fluid such as water in a rigid porous medium.
Journal ArticleDOI
Nonlinear Viscoelastic Model for Describing the Response of Asphalt Binders within the Context of a Gibbs-Potential–Based Thermodynamic Framework
TL;DR: The model developed in this paper is a generalization of the Oldroyd-B model and is used successfully to describe results of several experiments concerning the nonlinear response of asphalt binders, including nonlinear creep-recovery and stress-relaxation behavior, thinning behavior, and the appearance of normal forces perpendicular to the plane of shear in simple shear tests.
