Aim:
The objective of this course is to develop a broad understanding of deformation and fracture phenomena in metallic materials in the context of material processing and in-service performance. Mechanical behavior is approached through integration of the materials microstructure and continuum mechanics principles over a range of length scales. The course shall give knowledge about modern techniques for materials characterization and develop skills to evaluate the results from tests of the materials mechanical properties.
After completion of the course the students should be able to:
- Explain and describe basic concepts, relationships and models for deformation and failure mechanisms in metallic structural materials, (e.g. dislocation theory, creep mechanisms, basic fracture mechanics and fatigue theory)
- Apply the relationship between the materials microstructure and the mechanical properties, such as principles of strengthening mechanisms and micro-structural effects on fracture toughness, creep and fatigue 3. properties.
3
- Analyze and evaluate mechanical testing from an engineering perspective, especially creep testing, fatigue testing and fracture toughness testing.
4li>Analyze and explain real failures from a engineering materials perspective.
- Make assessments and generalize about the validity of different material models used in the strength and service life calculations of real components.

Organisation:
The course contains lectures, tutorials, home work assignments and a mandatory laboratory exercise. The lectures focus on the theoretical aspects connected to learning objectives 1 and 2. The main focus for the tutorials is to strengthen the students ability to independently solve problems associated to learning objectives 2 and 3. The home work assignment and the laboratory exercise will additional training in analyzing and evaluate the course the content with respect to learning objectives 3, 4 and 5.
