UW-Madison polymer processing (EPD650): lesson 5, part 4.

The penultimate part of lesson 5 concerns fitting a constitutive model to experimental data. The example that is given is fitting the Phan-Thien Tanner model's expression for apparent viscosity and first normal stress difference to experimental values of those parameters. The video discusses how to set up a spreadsheet to solve the problem and also introduces the concept of optimisation.
