Merging Experiment with Theory in Rheology
a two-day interactive tutorial.
Co-directed by: H. Henning Winter and Manfred H. Wagner
Contact H. Henning Winter <>
All lectures and tutorials are given in English.
Course Objectives and Prerequisites
The short course will build on the new teaching tools for rheology that became available with the IRIS rheology software. Short lectures on rheology will be combined with hands-on tutorials. The participants will learn to merge experiment and theory graphically on the PC screen. This approach allows us to introduce a wide audience the newest developments in rheology (linear and non-linear viscoelasticity of polymers). Our goal is that participants will master rheology on a quantitative level and also understand the underlying concepts that lead to the quantitative results. The only prerequisites for participants are basic computer knowledge (no computer language needed) and elementary knowledge in rheology.
Thursday all day: Short blackboard presentations alternate with hands-on practice sessions on the PC. Bring your own laptop PC for quantitative work on specific tasks. Tutorial data sets will be provided for all the practice. Tutorials start with data analysis (universal data standard, time-temperature superposition, time-resolved rheometry, exploration of material functions, relaxation time spectrum, retardation time spectrum, viscosity fit), continue with linear predictions from classical theories, show the power of some empirical models, and culminate in predictions from recent theory (tube dilation models of T. McLeish and coworkers; molecular stress function model of M. Wagner and coworkers).
Friday a.m.: Participants bring their own data and work on these with the help of tutors. The open class room environment allows sharing of successes and stumbling blocks. The session will end with a summary tutorial on problems that occurred during the morning session.
Friday p.m.: Further tutorials on the underlying concepts of the computer methods. Explorations of future developments: tutorial on extensional rheology and on material specific experimental methods
Support Material for the Short-Course
You will receive a booklet of course material and a copy of IRIS 8.0 to be installed on your labtop PC. IRIS 8.0 (http://rheology.tripod.com/) is a user-friendly platform that visualizes theory and experiments graphically. It is specifically written for teaching and researching dynamics simulations of rheology together with rheological data analysis. Use of IRIS 8.0 is free during the short course.
