AbstractPhysical properties and fracture mechanics of brittle materials.
Introduction to polymers.
ObjectiveThe composition and microstructures of the most important ceramic materials are introduced. Microstructures and heterogenous phase equilibria and the properties of the four most important structural ceramics and glass are given. An introduction to fracture mechanics of brittle materials will allow to predict the survival probabilities and life time of components under static and dynamic load.

To achieve a basic understanding for what polymers are like, how one can make them accessible and characterize them and, finally, which properties result from their chemical structure.
ContentThe basics of the chemical bonds of ceramics and glass will be presented. Heterogenous phase equilibria and the properties of the four most important structural ceramics are given. An introduction to fracture mechanics of brittle materials will allow to predict the survival probabilities and life time of components under static and dynamic load.

This introductory course discusses definitions, introduces types of polyreactions, and compares chain and step-growth polymerizations. It also treats the constitution of homo- and copolymers and networks as well as the configuration and conformation of polymers. Topics of interest are contour length, coil formation, the mobility in polymers, glass temperature, rubber elasticity, molecular weight distribution, energetics of polyreactions, and examples for polyreactions (polyadditions, polycondensations, polymerizations). Selected polymerization mechanisms and procedures are discussed. Some methods of molecular weight determination are introduced.
