Modules

Prerequisites

Contents

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.

Learning outcomes

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.

Assessment

• Oral examination, 60 minutes OR Written examination, 120 minutes In the first lecture it will be announced, if he examination will be offered in written or oral form.
