Overview: This paper presents the outcomes of computational mechanics applied in the root-cause investigation on blade failures of an auxiliary steam turbine in a domestic power plant, in which cracks were detected at the tenon region on the blades during scheduled outages. This involves the calculated data of the finite-element models are benchmarked with the corresponding modal testing results, which show a reasonable agreement between the analysis and experiment. This outcome confirms the suitability of the present models and the methodology. In general, the computational mechanics can be regarded as a valuable tool for the root-cause investigation of component failures in power plant equipment.
