AbstractThe course approaches failures in metallic, ceramic and polymer components as well as structures.
Objective1) Understanding common failure mechanisms of materials and structures

2) Obtaining knowledge about the methodology of failure analysis

3) Learning to apply the different investigation methods appropriately
ContentSTRUCTURES: In most failure cases, the material used is only one of various aspects to be considered. Consequently, successful failure analysis requires a comprehensive interdisciplinary approach. The systematic procedure, which involves the preservation of evidence, followed by establishing and evaluating hypotheses and completed by drawing conclusions, will be explored interactively, based on variegated failure cases.

METALS: After a brief overview of the most failure-relevant properties of metallic materials, focusing on steel, different common failure mechanisms and the related investigation approaches will be demonstrated based on case studies from different fields like transportation, machinery and building structures.

CERAMICS: Ceramics are used in applications where electrical insulation, resistance to wear, or the ability to withstand high temperatures are needed. Failure mechanisms in ceramic components under operating conditions are analyzed: corrosion due to fluids, erosion due to fluids loaded with particles, hot gas corrosion, creep.

POLYMERS: Methodology of failure analysis on polymer materials: system approach, mechanisms like aging in polymers, analysis of thermoplast, thermosets and elastomer failures based on application oriented cases. Team exercises on selected failure cases.
Prerequisites / NoticeUntil further notice, this lecture will take place online. Further information is given on moodle.
