Extension-Inflation-Torsion Test Bench
Force (1 axis), Torsion (1 axis), Pressure, Displacement (1 axis), Rotation (1 axis)
Test types:
Extension-inflation-torsion
FIBEr
Model: Testing Machine for Tubular Biomaterials
Manufacturer: ZwickRoell
About
The extension-inflation-torsion tester can load a sample triaxially by applying a hydraulic pressure, uniaxial tension or compression and a torsion angle. It is used to test tubular samples (e.g. arteries) in their intact shape, but also for a bulge-inflation test or unconfined compression-torsion test.
