Description

This course is divided into two parts: First the discussion of the mechanical properties of materials and their structural origin (supplement to Materials I-III). The second focus is on materials' selection according to their physical and mechanical behaviour as well as other boundary conditions.

•   The mechanical properties of materials (strength, stiffness, toughness, ductility, and so on) and their structural origins are discussed. The relationship of the elastic, plastic and fracture behaviour to microscopic structure in metals, ceramics, polymers and composite materials is explained. Effects of time and temperature on materials properties are discussed. Bauschinger theory, isotropic and kinematic hardening, elastic-plastic deformation, fracture deformation. Cyclic loading: fatigue strength, influences on fatigue strength, damage accumulation, cyclic stress-strain-curve, cyclic elastic-plastic deformation.

•    Materials selection for engineering applications: Methods to select materials for engineering applications, emphasising structural and thermal properties. Fundamentals of the interrelation between material parameters. Strategies for optimal selection subject to performance, processing and manufacturing constraints. Materials selection with and without shape considerations. Use of materials' databases. Design case studies. Materials synthesis methodologies.
