Welcome to the
home of the DYNAMET bi-axial fatigue system
WHY DYNAMIC BUBBLE INFLATION?
Stretch frames, used for the bi-axial tensile testing of rubber are limited by:
- Clamping effects.
- Specimen dimensions.
- Extension ratios that can be achieved.
- Loading frequencies for dynamic tests.
- Friction and inertia effects
BUBBLE INFLATION PROVIDES
- Large equi-biaxial deformation at the bubble pole where failure occurs and stresses and strains are readily measured.
- Tests can be carried out over a range of frequencies, (typically 1-10Hz for all rubber compounds) for a controlled number of cycles or until sample failure.
- Specimens can be loaded multi-axially to fixed upper control limits (stress, pressure, strain) for a specified number of cycles or until sample failure.
CER are currently developing CAPRICE, the next generation multiaxial dynamamic analysis system for advanced elastomers (Enterprise Ireland Funded).
