Creep acceleration induced by microstructure degradation is incorporated in the material model that describes the nucleation and growth of cavities in the grain boundary, including the effect of diffusion, dislocation creep and grain boundary sliding. It is found that the creep acceleration significantly reduces the notch sensitivity of the material.
