Defining nonlinear rheological material functions for oscillatory shear

RH Ewoldt - Journal of Rheology, 2013 - pubs.aip.org
Material functions underlie our understanding of rheology. They form the descriptive
language of rheologists and require clear definitions. Here, it is shown that the definitions of …
