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
Due to the COVID-19 crisis, the information in this section is particularly likely to change.A combination of :
- Ex cathedra courses : concepts are illustrated by concrete exemples taken from industrial practice and the experience of the teachers.
- Rheometry laboratory and/or processing simulation project
- seminars prepared and presented by the students
- Laboratory and plant visits
Due to the COVID-19 crisis, the information in this section is particularly likely to change.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%)
