This is a mechanical testing setup designed to enable controlled biaxial testing of metallic foils and thin laminates in order to facilitate evaluating material formability and characterizing the biaxial stress/strain response of the material. The setup adapts to most modern universal load frames and converts the machine’s crosshead motion into pressurized fluid that is used to drive material deformation within a bulging setup. Tension testing of metallic foils and thin laminates is not an easy task due to edge effect; this setup enables a more robust way of characterizing these materials for critical applications such as the Battery industry.
Adaptability: Most universal load frames (20kN or higher) with modern electronics and an I/O card (INSTRON, ZwickRoell) as well as most servohydraulic presses (Interlaken)
Force Limit: 50kN
Max Test Speed*: ~100 mm/s
Max Foil Thickness: ~400microns
Testing Directions: Compression
