Contribution of the course to the program objectives
Axis 1: 1.1, 1.2
Identify and implement the concepts, laws, reasoning applicable to a problem; develop and use the appropriate modeling and calculation tools to solve a problem.
Axis 3: 3.1, 3.2
Search in the literature, summarize and present the current state of knowledge on a specific issue related to the rheology of polymer melts.
Measuring and modeling the viscoelastic properties of polymer melts.
Axis 4: 4.2, 4.4
Write reports on practical works and present a specific topic related to rheology by group of 2 students.
Axis 5: 5.3, 5.4, 5.6
Communicating in a schematic form, Interpreting and presenting in an accurate way a new concept in rheology, based on a scientific publication.
I. Introduction  : industrial polymer processing, non Newtonian fluids, continuum mechanics refresher
II. Shear viscosity, normal forces and elongational viscosity: observations and phenomenological models
III. Flow through a channel
IV. Capillary rheometry and extrusion defects
V. Origin of viscoelastic effects; notions of rheological models; introduction to processing flow simulation
VI. Cone-plate and plate-plate rheometric flow; Elongational flow
VII Major industrial polymer processing operations : rheological aspects, technology and applications
Teaching methods
A combination of :
  1. Ex cathedra courses : concepts are illustrated by concrete exemples taken from industrial practice and the experience of the teachers.
  2. Rheometry laboratory and/or processing simulation project
  3. seminars prepared and presented by the students
  4. Laboratory and plant visits 
Evaluation methods
The students will be individually graded based on the objectives indicated above. More precisely, the evaluation involves the grading of :
  • The presentation of a project in groups of two or three on a topic linked to the course content. This project will carry 20% of the total mark.
  • Few practical works and lab (10%)
  • Oral exam (70%)
