Research
One project in ourgroup supported by CIMM is studying fatigue crack initiation and growth in metals and composites. Thermomechanical fatigue including entropy and plastic strain accumulation are being investigated.Damage mechanics as well as fracturemechanics software simulations are carried out. The experimental fatigue tests for multi-sensor data based fatigue crack prognostics are carried out using servo-hydraulic MTS mechanical test machine. Failed specimens are further investigated using optical microscopy and SEM, for confirmation of marker bands, phases and grain structure. Prognostics system for fatigue crack growth/life tracking will be developed.
