In this course, the students will be introduced to the foundamental concepts, theories, computations as well as applications of fracture mechanics. It will start with the foundemantal phenomenon of fracture behaviour in materials followed by the analysitical solutions of linear elastic fractures under different fracture modes. Experimental characterization methods of fracture toughness will be disucssed and the concept of stress intensity factors and state of the art methods for modelling fractures will be introduced. Current availabe software that can be used for fracture modelling and their limiations will be shown and discussed.

Graduates at the end of this course should be familiar with the physical and mechanical model and definition of fracture problems especially in linear elastic fracture mechanics. They will be qaulified for the problem identification of fractures, model setup and computational of materials with fracture. At the end of the course, the students are expeted to be able to select the appropriate criteria and model in analyzing engineering fracture problems, and understand the validity and limits of their results. They shall be experienced on understanding and discussing the state of the art literature in the engineering fracture mechanics and on the defence of their findings by an oral presentation of a selected problem.

The lecture gives an overview on theory, methods and devices in optical metrology. At the beginning, fundamentals of optics and photonics such as ray and wave optics are revised, which are essential for the understanding of concepts in optical metrology. Focusing on metrology in research and industrial applications, the lecture covers optical methods for measurement of topography, distance, and deformation as well as fiber optical sensors, which include concepts such as interferometry, holography and confocal microscopy. In addition, semi-optical methods such as atomic force microscopy and near field microscopy are addressed and compared to non-optical methods, e.g., scanning electron microscopy. To gain an in-depth understanding of the concepts involved in optical metrology, all devices and optical setups are explained in detail including light sources, cameras, and optical elements.
