The fracture behavior of many materials is dependent on, among other things, the loading rate. Relevant data and constitutive equations are required for the numerical calculation of crash safety. The HTM series of servohydraulic high-speed testing machines allow strain-rate-dependent characteristic values to be determined over a wide speed range. Uses for machine include puncture tests and high-speed tensile tests, as well as peel, and shear tests at high speeds. Tests on components can also be performed in conjunction with the optional T-slotted platform.

High-speed testing machines form a complete system with all components - including the hydraulic power pack, test frame with high-speed testing actuator and safety housing, fast measurement and control electronics with PC and evaluation software—matched and integrated.

• The HTM series is available in various versions with maximum test loads of 25, 50, 80 or 160 kN.
• The maximum piston speed is 20 m/sec. For testing, this can be selected from a wide range from very slow to maximum speed.
• The testing machine can be supplied for 280 bar system pressure.
• testControl measurement and control electronics in addition to testXpert III testing software enable comprehensive test result evaluation, report creation and data management.

Advantages & Features

• With testXpert a uniform software platform is available, from test definition right through to evaluation.
• Easy integration of optical extensometers.
• Machine is mounted on pneumatic springs, allowing installation almost anywhere.
