Torrent description

These are notes for a course of basic Rheology. The text is in English but with some words translated to French since it was originally targeted to Polymers Science students of Aix-Marseille University. As the title says, equations and theoretical models are reduced to the bare minimum, in the attempt to help the reader to understand as much as possible the Physics behind rheological measurements.

Table of contents


Basics of Rheology
1.1 Stress and strain. Definitions and measurement in a rheological test
1.2 The Hookean response or the ideal elastic solid: simple deformation.
1.3 The Newtonian response or the ideal viscous fluid: simple flow.
1.4 Models and Greek letters

Flow characterisation
2.1 Flow curves – the non ideal behaviour of viscous materials
2.2 Dependence of viscosity on polymer molecular weight
2.3 Shear and extensional viscosity

Creep analysis
3.1 What is creep?
3.2 Principle of operation of a creep test
3.3 Time scales and the Deborah Number
3.4 Linear amorphous polymers creep: time is money, temperature is time
3.5 Zero shear viscosity: measurement by creep test

Viscoelastic oscillatory characterisation
4.1 Linear viscoelastic region
