| Abstract Scope |
There are numerous applications in the modern engineering world which involve the use of metals under conditions of cyclic loading in operating conditions that can cause creep and/or environmental interactions with time independent, mechanical fatigue processes. Various approaches for modeling the creep-fatigue crack growth behavior have been proposed to capture the various types of damage that is occurring. These include mechanistic modeling, crack growth modeling using the method of superposition to incorporate time-dependent and cycle-dependent components, and numerical modeling. A number of phenomena have been investigated to obtain a better understanding of the fundamental creep-fatigue crack growth process. The various models and techniques used in modeling the elevated temperature creep-fatigue crack growth process will be reviewed. |
