Filament Stretching Extensional Rheometer (FISER)
Based around linear motion control system with real-time force and midpoint radius data acquisition.
- Tirtaatmadja & Sridhar (1993)
- Impose kinematics that ensure fluid elements at midplane undergo ideal uniaxial deformation
- Hencky strains of up to e 7 and rates up to 20 s-1 are typically achievable.
