Matter is commonly found in the form of materials Analytical mechanics turned its back upon
this fact, creating the centrally useful but abstract concepts of the mass point and the rigid …

Normal-stress effects and the variation of apparent viscosity with rate of shear in simple
types of steady flow of certain idealized elastico-viscous liquids are discussed. The liquids …

Many foods have a yield stress that allows them to retain a desired shape at rest, but
transition into a viscous fluid when being served or consumed. The determination of the …

We propose a microscopic theory of light-induced deformation of side-chain azobenzene
polymers taking into account the internal structure of polymer chains. Our theory is based on …

Graphene oxide (GO) has attracted attention in materials science and engineering due to its
large aspect ratio and dispersibility in polar solvent including water. It has recently been …

Long glass fiber-filled polypropylene (PP) composites are produced by pultrusion, and the
extrudate is cut at different lengths producing composites containing long fibers of controlled …

1. Introduction. The purpose of this paper is to point out that, in the case of rectilinear motion,
Rivlin's theory of non-Newtonian fluids [1] yields two partial differential equations for …

The decade following the second world war heralded the publication of a collection of
important papers on non-Newtonian fluid mechanics; Oldroyd's work featured heavily in this …

A difficulty in any flow calculation with viscoplastic fluids such as Bingham fluids is the
determination of possible plug zones in which no deformation occurs. This paper …

We consider a class of simple materials characterized by a history-dependent viscosity
tensor which we call purely dissipative. These materials encompass several existing models …
