A continuum model for the creep of single crystal nickel-base superalloys

TL;DR: In this paper, the authors developed a constitutive theory within a thermodynamic setting to describe the creep of single crystal superalloys that gainfully exploits the fact that the configuration that the body would attain on the removal of the external stimuli, referred to as the "natural configuration", evolves, with the response of the body being elastic from these evolving natural configurations.
Journal ArticleDOI

Chemorheological Relaxation, Residual Stress, and Permanent Set Arising in Radial Deformation of Elastomeric Hollow Spheres

TL;DR: In this paper, a hollow sphere composed of such a material, also assumed to be incom-pressible and isotropic, which undergoes axisymmetric deformation under radial traction is considered.
Journal ArticleDOI

A mathematical model to describe the change in the constitutive character of blood due to platelet activation

TL;DR: There is a need to develop a mathematical model for the flow of blood that takes into account platelet activation, no such model being available at the moment.
Journal ArticleDOI

A new class of quasi-linear models for describing the nonlinear viscoelastic response of materials

TL;DR: In this article, a new class of quasi-linear viscoelastic models is proposed, where the linearized strain is expressed in terms of a nonlinear measure of the stress.
Journal ArticleDOI

Stress softening, strain localization and permanent set in the circumferential shear of an incompressible elastomeric cylinder

TL;DR: In this article, the authors considered a hollow circular cylinder composed of such a material, also assumed to be incompressible and isotropic, and found that microstructural scission can lead to higher levels of shear deformation near the inner surface of the cylinder than in the case of purely elastic response.
