Subject aims expressed by acquired skills and competences
The aim of the course is to make students familiar with basic principles of failure analysis on failed or damaged components. Students will learn general procedures of an optimal solution of problems and to prepare a technical report summarising analysis results. The course also includes the topic of precautions and prevention.

Summary
Students will learn about basic aims and procedures of investigations on failed components, including proposals of precautions and preventive measures. Failure analysis will be demonstrated on study cases. Basic rules of processing of failure analysis results will be defined.

3. Analysis of failures: imperfections in design, material defects, overloading or improper loading of components, insufficient maintenance, unskilled repairs, interaction between material and environment.
4. Degradation effects related to technological operations (heat treatment, welding) on materials properties.
5. Overload failures – possible mechanisms. A study case of overload failures.
6. Fatigue and creep failures. A study case of fatigue and creep failures.
7. Corrosion failures – possible mechanisms. A study case of corrosion failures.
8. Wear failures – possible mechanisms. A study case.
9. Experimental techniques for bulk and local analyses of chemical composition of materials.
10. Experimental techniques for structure characterization and for investigations on micromechanisms of fracture.
11. Experimental evaluation of mechanical properties of materials.
12. Applications of modelling and simulations in failure analysis.
13. Proposal of precautions and their validation. Prevention.
14. Basic rules for preparation of the report summarising results of failure analysis.
