Learning outcomes:
Using their knowledge about the main failure mechanisms and their causes, students will be able to:
  - Systematically perform a damage analysis
  - Select suitable test methods in a targeted manner
  - Integrate and evaluate their results into the overall analysis procedure
  - Reconstruct the failure process
