Based on the patented Kappa 100 SS-CF creep test machine
, ZwickRoell now also provides a precisely controlled test solution, with which thermo-mechanical material fatigue can be simulated. The material is inductively heated, the hydraulic grips and the HT extensometer are water cooled for protection from the high temperatures. A TMF controller synchronizes mechanical and thermal loading. As an alternative system combination, the Kappa 100 SS-CF is used with a 3-zone furnace for temperatures up to 1,200 °C. With these testing systems, material fatigue and crack growth are simulated through variable cyclic loads. A contact-type HT extensometer, which is also water-cooled, is used to record deformation. The test programs for creep-fatigue test, such as creep crack growth (CCG), low-cycle fatigue (LCF), creep-fatigue (CF), fatigue crack growth rates (FCGR) and creep-fatigue crack growth (CFGR) are included in testXpert R.
