A Nonlinear Fracture Mechanics Approach to Crack Propagation in the Creep-Fatigue Interaction Range
High temperature fatigue tests were conducted with center cracked thin-walled cylindrical specimens in a closed-loop servo hydraulic testing machine. The applicability of nonlinear fracture mechanics to the time-dependent as well as the cycle-dependent fatigue crack propagation was determined, using creep J-integral and fatigue J-integral.
