DYNAMET

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).
