Thierry Palin-Luc: Discussion on the Physical Significance of the Gigacycle Fatigue Strength of a Cast Aluminium Alloy and a Titanium Alloy

Under the aegis of the Medicis programme Abstract Surface plays a key role in the fatigue strength of metallic alloys, especially in high cycle fatigue regime (1E6 – 1E7 cycles) because material defects are present at the surface or in the subsurface of components. But, internal fatigue crack initiation and growth are very often observed … Lire plus

Quentin Bourgogne : Études de l’influence de l’environnement de sollicitation sur les propriétés physiques et mécaniques de polymères et composites renforcés de fibres synthétiques et naturelle

Résumé La démocratisation de l’utilisation des composites à base polymère s’étend dans l’industrie aéronautique et automobile jusqu’à atteindre dans certains cas 50% de la masse totale du moyen de transport. Ces matériaux se heurtent encore aux applications dites sous-capot, proches du bloc moteur, où les températures de sollicitations et l’immersion en permanence dans de l’eau … Lire plus

Frédéric Magniez : Algorithmique quantique : des fondements aux applications

Sous l’égide du programme Medicis Résumé Tous les calculs informatiques sont actuellement exécutés sur des ordinateurs contraints par les lois de la physique newtonienne, aussi appelée physique classique. Cependant, comme l’a suggéré Richard Feynman dans les années 80, un ordinateur quantique, utilisant pleinement les possibilités et paradoxes de la physique quantique, pourrait accélérer certains calculs, … Lire plus

Min Zhou: Effects of Microstructure and Voids on the Shock-to-Detonation Transition Behavior of Energetic Materials

Under the aegis of the Medicis programme Resume Microstructure and voids profoundly influence the behavior of materials under a variety of thermal, mechanical, optical, or electromagnetic stimuli. For structural materials, the effects manifest through deformation, failure, and energy dissipation. For metamaterials, the effects can be on the propagation of stress, acoustic, and electromagnetic waves. For … Lire plus
