Crack Growth Modeling

The general scheme of crack growth modeling and periodicity of aviation structure elements checks was developed. The major factors determined the scale of inaccuracy calculation ( εN*) based on calculations of crack growth duration (N*) and inspections intervals (τ0) were marked and estimated with the block diagram.

Crack Growth Modeling

Thermomechanical fatigue (TMF) crack growth modeling has been conducted on Inconel 718 with dwell time at maximum load. A history dependent damage model taking dwell damage into account, developed under isothermal conditions, has been extended for TMF conditions. Parameter determination for the model is carried out on isothermal load controlled tests at 550–650 °C for surface cracks, which later have been used to extrapolate parameters used for TMF crack growth. Further, validation of the developed model is conducted on a notched specimen subjected to strain control at 50–550 °C. Satisfying results are gained within reasonable scatter level compared for test and simulated number of cycles to failure.
