Thermo-Mechanical Fatigue (TMF) testing simulates the complex effects of simultaneous thermal and mechanical strain and is able to replicate the service conditions experienced by gas turbines and the infrastructure associated with power generation.
More sophisticated than isothermal fatigue, TMF uses induction heating and forced cooling to achieve specimen heating and cooling rates in excess of 50°C/s.
SMaRT currently has 4 test rigs capable of conducting
load or strain controlled TMF tests and is developing
the capability to perform crack propagation testing
under TMF conditions.
