Extensional viscosity

Extensional viscosity is a viscosity coefficient when applied stress is extensional stress. [1].

This parameter is often used for characterizing polymer solutions.

Additional recommended knowledge

Extensional viscosity can be measured using rheometers that apply extensional stress. Acoustic rheometer is one example of such devices.
