Servo Hydraulic Testing Machines

Servo (Dynamic) hydraulic universal testing machines which are used in a variety of tests like tension compression flexure fatigue (low cycle fatigue / high cycle fatigue / fatigue crack propagation ASTM E647), fracture mechanics (K1c per ASTM E399, J1c, CTOD per ASTM E-1290), damping properties and vibration testing. Our test systems are designed for conducting tests at ambient temperature, elevated temperature (high temperature fatigue characterization) and low temperature. Test speed range slow strain rate testing (typical of corrosion interaction)(1 x 10 -7 /s strain rate) high strain rate testing (flow deformation studies).(150 /s true strain rate) The testing machines are fitted with servo-controlled pumps that come in two versions: hard-wired autonomous control with electronic setting of operating high and low pressure. Operating pressure is set with the convenience of on-screen graphics user interface. Technical features of our hydraulic materials test systems are: * Metals, composites and polymers * Low cycle fatigue (as per ASTM E606) * Fracture mechanics including fatigue crack growth (as per ASTM E647 and E1820). * Room temperature and high temperature testing * Testing in corrosive media * Fully self -contained test system packaged for easy relocation and movement * Load frame on vibration isolators * No additional utilities required. Simply plug into 3- phase mains and commence testing
