Thermal fatigue analysis on cracked plenum barrier plate of open-cycle gas turbine frame

Failure investigation is carried out following repeating findings of several obvious surface-crack spots on the weld joint zone of a plenum barrier plate of open-cycle gas turbine frame. The exhausted hot compressed air will flow through the cracks entering the load compartment which contains temper...
