Extensional viscosity
From Wikipedia, the free encyclopedia
This article is about extensional viscosity. For other uses, see Rheology.
Extensional viscosity is a viscosity coefficient when applied stress is extensional stress. [1].
- This parameter is often used for characterizing polymer solutions.
Extensional viscosity can be measured using rheometers that apply extensional stress. Acoustic rheometer is one example of such devices.
