title = "A comparative study of a single damage-parameter life prediction method and a physically-based damage mechanics method",
abstract = "This paper presents a comparison between the life predictions from a physically-based damage mechanics formulation, which captures the fracture mechanism of intergranular cavitation, via three state variables, describing intergranular creep cavitation, coarsening of carbide precipitates and primary creep softening, and a corresponding single-damage mechanics formulation, of the Kachanov-type. The comparison is made for a 0.5Cr0.5Mo0.25V ferritic steel at a temperature of 635°C across a range of stress levels on the basis of a notched bar stress-state. Simplified predictions based on the R5 reference stress method are also given for comparative purposes.",
