Abstract
A tensile ligament instability model for creep controlled crack growth , based on Krafft, and Hart and Li, is used to illustrate the approach in formulating a mechanistically based probability model for life pre diction. Such a model is needed for making statistically accurate esti mates of service life for conditions not included within typical suppo rting design data. The approach and methodology for model development are described. The contributions and significance of selected fundamen tal variables for the deformation and failure processes are discussed.
