A creep–fatigue crack growth on the outer surfaces of a turbine casing was assessed, and the turbine casing’s overall lifetime was predicted. The crack location, size, and direction were determined using nondestructive tests. Temperature distribution, measured using thermography method, was applied as boundary conditions in FEM simulation. ABAQUS software was utilized for calculating the stress distribution of the casing in accordance with the real cycles of the turbine. Both the creep and the fatigue crack growths were predicted using the ZENCRACK code. The Paris equation was applied in order to estimate the fatigue life, and the time-dependent Paris equation was used to predict the creep life. It was shown that after a certain amount of time has passed, the crack stress intensity factor (K) and time-dependent stress intensity factor (Ct) decrease and stop in reaching the fatigue threshold stress intensity factor (Kth) and creep fracture mechanics parameter (C t * ) values, respectively.
