This Master’s Degree Thesis focus is the Dynamic Characterization of a Gas Turbine Blade produced by Ansaldo Energia S.p.A in two different materials, in particular a first series made of material René 80 and one in Inconel IN792DS material. The blade is part of a single stage of a complete turbine that is used for energy production, with the specific blade in exam being part of the third-stage of the turbine part of the machine. Due to the different properties of the aforementioned materials, the associated behaviour will be different, resulting in a different Modal solution and a different vibrational pattern.
