Materialwissenschaft II (327-0401-00 )

Goal:

The aim of the first part of this lecture is to get insight in the description of mechanical properties of brittle materials and their statistical nature including toughening concepts for ceramics.

Contents (for the ceramic part of the lecture):

• Introduction to brittle behaviour of materials (ceramics)
• Stress intensity factor
• Flaws in ceramics and fracture strength of components
• Slow crack growth
• Life time prediction of ceramic components under cyclic load and design guidelines for ceramic components: A case study
• Proof testing
• Creep
• Thermal shock
• Toughening concepts for ceramics
