The dispersion of fillers in rubber is still an issue for the industry: industrial products usually contain defects such as filler agglomerates, which can cause their premature failure. Recently, industrials have started to explore nondestructive tec

Fatigue is the main phenomenon causing the failure of mechanical structures. For very long service lives the initiation of cracks leading to the failure of in service mechanical parts changes from surface to volume. Due to experimental difficulties t

Crystalline silicon has attracted substantial attention for decades because of its large applications in solar cells and microelectromechanical systems. The high brittleness of silicon raises wide concerns since the failure of this semiconductor mate

To guarantee the high level of safety of industrial components under fatigue cycles it is essential to be able to predict the initiation and growth of cracks during their entire lifetime. However the numerical cost of a propagation simulation on engi

Les alliages d'aluminium utilisés dans les structures aéronautiques (fuselage, voilure) sont soumis à des chargements cycliques, faisant de la fatigue l'un des facteurs dimensionnant. Dans cette thèse, les mécanismes d'amorçage de ces fissures

Aluminium alloys used for aerospace structures (wing, fuselage) are subjected to cyclic loading. Fatigue properties of such alloys are therefore taken into account for the design of such parts. In this thesis, initiation mechanisms of fatigue cracks

Cette thèse porte sur l’influence des transformations de phases solide-solide sur la propagation de fissure. On souhaite ainsi mieux comprendre les variations de ténacité en cours de soudage par exemple, ou bien pendant la réparation d’une fi

Ou study focuses on the effects of phase transformations on crack propagation. We want to understand the changes of fracture toughness during welding. In this work, fracture toughness is expressed by J-integral. There are many experimental methods to

Il est connu depuis des décennies que la propagation des fissures de fatigue dans les matériaux élastoplastiques est très sensible à l’histoire du chargement car le comportement non-linéaire du matériau peut avoir une grande influence sur le

It has been known for decades that fatigue crack propagation in elastic-plastic media is very sensitive to load history since the nonlinear behavior of the material can have a great influence on propagation rates. However, the raw computation of mill
