Thermal cycling and mechanical fatigue tested
Instron is introducing the 8862 thermo-mechanical fatigue (TMF) system designed for both low cycle fatigue and slow strain rate testing
The 8862 has a 100kN high-stiffness, precision-aligned load frame and a single ballscrew 100kN electromechanical actuator.
This combination provides a superior testing system designed for both low cycle fatigue and slow strain rate testing.
To simulate testing in extreme heat followed by rapid cooling, Instron's TMF systems feature an induction heater, as well as water-cooled hydraulic grips.
The 8862 utilises Instron's FastTrack 8800 controller, which provides the accurate control needed for complex thermo-mechanical fatigue testing.
The system is controlled through FastTrack TMF software package, which can automatically compensate for thermal strain.
To ensure accurate, repeatable test results, the 8862 features Instron's patented Dynacell.
This innovative load-cell prevents inertial load errors, because it is equipped with an accelerometer designed to measure and compensate for load-cell/grip inertia.
