| Abstract | To reduce aircraft weight and improve engine efficiency, it is still necessary to optimize metallic aeronautical materials. One solution is to control their crystalline microstructure to optimize their physical properties. However, the precise characteristics of the microstructure that drive material behavior, such as fatigue resistance, are not fully understood at this stage. The aim of this thesis is to study the initiation and micro-propagation of fatigue cracks using numerical simulations, taking precise microstructural characteristics into account. At present, very little account is taken of these microstructural properties, leading to considerable inaccuracies in constitutive behavior predictions. In particular, the aim of this thesis is to develop a simulation method capable of predicting the service life of aeronautical materials, such as nickel-based superalloys, using numerical characterization of their microstructure, including real sources of cracking such as grain boundaries, twin boundaries and inclusions. |
