Mechanical behaviour at high strain rates differs considerably from that observed at quasi-static or intermediate strain rates,
and many engineering applications require characterization of mechanical behaviour under dynamic conditions.
Our servohydraulic high-speed test systems provide loading and strain-rates over a wide range. The systems are designed to for tension or compression tests on metals, plastics and other materials at ambient temperature or in combination with environmental chamber.
Models with actuator mounted on upper crosshead or on machines base are available. Typically used actuator stoke is 250 mm plus 70 mm cushioning on each side. Directly on the actuator high responsive servovalves are attached with accumulators providing high flow rates and minimizing hydraulic pressure fluctuations. The system incorporates a high-speed high-rigid piezo-electric load measurement and data acquisition system.
