N2 - In this paper, creep crack growth simulations were performed based on finite element (FE) damage simulations for several types of test specimens such as C(T), CS(T), SEN(T), M(T) and SEN(B). The Graham-Walles creep law was adopted to describe all three phases of creep. The Creep parameters were obtained from uni-axial creep test results of SS316H at 550oC. Damage model was also included based on creep ductility exhaustion concept, which is defined as the ratio of creep strain to the multi-axial creep ductility. Creep crack growth rates resulting from FE simulations were compared with the experimental data.
