Introduction to Deformation&Fracture Mechanisms in Crystalline&Amorphous Materials (IMECH)
Classification: Materials science (D), general background
Lecturer: Erik Bitzek
Language: English
Contents:

* Microstructure and defects in crystals: vacancies, dislocations, grain boundaries
* Characterization of and defects in amorphous materials
* Brittle crack propagation in crystals (metals, ceramics) and amorphous materials (metallic and inorganic glasses, polymers)
* Ductile fracture in metals
* Fracture in polymers
* Stress corrosion cracking
* Nucleation and propagation of fatigue cracks

Objectives:
The students

* can describe and characterize the microstructure and defects in various classes of materials and are familiar with the properties of different types of defects
* can classify materials according to their intrinsic, theoretical ductility/brittleness
* are familiar with the concept of lattice or bond trapping and kink mobility
* can describe the atomic- and meso-scale deformation mechanisms in crystals, metallic and inorganic glasses and polymers (e.g., dislocations, shear transformation zones, shear bands, void formation, crazing,…)
* know the processes during stress corrosion cracking and can model subcritical crack growth
* can describe the mechanisms leading to crack nucleation and growth during fatigue of metals, ceramics, engineering plastics and composites
