Thermal cyclic behavior and lifetime prediction of self-healing thermal barrier coatings

The thermal cyclic behavior of self-healing thermal barrier coatings (SH-TBC) is analyzed numerically to develop a lifetime prediction model. Representative microstructures are studied adopting a unit cell based multiscale modeling approach along with a simplified evolution model for the thermally-grown oxide layer (TGO) to study the...

Useful lifetime prediction software for plane semi-cracks in 3-D solid configurations

Computer programs are described to be used for fracture control purposes. Crack growth lifetimes can be predicted for plane cracks in 3-D structures. Values for stress intensity (K-) distributions at crack fronts are derived from data being available from literature for a restricted number of simple configurations. For arbitrary configurations...

Lasting Friendship: A review of the F-27 fatique evaluation programma carried out by Fokker-VFW

Fokker-VFW is carrying out a completely new fatigue evaluation of the F-2T aircraft, covering lives up to 120000 flights. This evaluation includes; a)A complete inventory of the configuration status of the F-2T fleet, b)An inventory and evaluation of existing test experience, c)Evaluation of service experience, d)Analytical predictions of life...
