The students will learn about the fundamentals of life prediction methods as they are applied in the automotive and aero-engine industry. The students will be enabled to do some first calculations to establish the life of a component until crack initiation. Furthermore, the introduction into fracture mechanics, that are methods to predict the crack propagation, will allow the life calculation of a component until it finally fractures.
Damage mechanisms, nominal stress concept, local stress concept, linear and non-linear damage models, damage parameters, multiaxial fatigue, linear and non-linear damage accumulation, counting methods, validation, J-integral, Paris law, legal requirements and means of compliance, examples of aero-engine and piston engine components, research topics.
