Summary
The different fracture mechanisms of structural materials are explained. The course consists of five main chapters: - Introduction: fracture and failure, what's the difference? the different types of damage in various industrial sectors - influence of temperature and stress on the different types of fractures: cleavage, ductile fracture, creep fracture, fracture map - fatigue fracture: onset and growth; cyclic accommodation, fatigue resistance diagrams, dislocation structures, short cracks, the different long crack growth models, plasticity at the bottom of the crack, closure effect - fracture mechanisms assisted by the environment: stress corrosion, hydrogen embrittlement, liquid metal embrittlement, irradiation embrittlement, corrosion fatigue - wear damage mechanism: adhesion, erosion, abrasion
Educational goals
The aim of the course is to understand the damage mechanisms of structural materials (in particular those used in the chemical industry and the energy and transport industries) resulting from mechanical loadings and a corrosive environment. The purpose of the course is to show the importance of the microstructure regarding these types of damage. Students will be able to use this knowledge to solve component failure assessments, which are useful for the safety of industrial installations. They will be able to: - identify the nature of the damage to a material in service - identify a fracture type on a worn-out component in service - explain the cause of damage to a component in service - suggest the most suitable material to optimise reliability
