Introduction & Scope
If this movie does not display,
A brief survey of developments in extensional rheometry of ‘mobile liquids’ since 1990.
- The Falling Plate Rheometer
- Matta & Tytus, JNNFM, 1990
- “Spinnable materials are distinguished above all by the fact that, under suitable conditions, they show elasticity in tension to such an extent that one is led to consider them at least in some respects to be more like solids than liquids”; Fano (1908) – Tanner & Walters, Rheology: An Historical Perspective, 1998.
- The Liquid Filament Microrheometer
- Bazilevsky, Rozhkov & Entov, JNNFM, 1990
- Monitor the subsequent necking and breakup of the liquid filament under capillarity...
- A principal focus has been on understanding kinematics and optimizing designs to achieve a true homogeneous uniaxial elongation.
