    Abstract

    In this paper, the FE damage analysis method, proposed in Part I, is applied to simulate creep crack growth in six different types of cracked specimens of 316H at 550. °C. Comparison with experimental results shows that simulated creep crack growth rates agree well with experimental data. Shortcomings of the present method to predict creep crack initiation is briefly discussed.
