Abstract
This course provides the fundamentals for understanding the mechanical properties of different classes of materials. The role played by the nano- and microstructure of the materials, how the mechanical properties are influenced by the composition or processing, as well as which methods can be used to determine material-specific mechanical parameters are examined.
Objective
The students are able to - Apply the interplay of structure and properties in the selection and development of materials. - Understand plasticity, crack growth, high temperature properties, corrosion, diffusion, environmental influences, grain growth, fatigue, fracture mechanics across material classes. - to adjust mechanical properties in a targeted manner. - to select and develop the optimal materials for specific application areas by understanding the temperature-dependent material properties. - take measures to increase the service life of materials. - to link the similarities and differences of the various classes of materials. - understand concepts of material development and apply them to new materials.
Content
This lecture has the irreversible mechanical deformation of materials as its core topic. Independent of the material classes, the following phenomena are explained in detail and rigorously derived: Crystal plasticity at low temperatures (dislocation theory, hardening mechanisms, twinning, brittle-ductile transitions), plasticity in disordered structures (shear bands and strain localisation), Fracture mechanics (Griffith criterion, Weibull statistics, crack tip plasticity, J-integral, R-curve), fatigue (Wöhler curves and Paris law), environmental influences, high temperature plasticity (creep and deformation mechanism diagrams). All phenomena are illustrated by actual case studies using concrete materials and material systems. These include aluminium alloys, steels, high temperature alloys, advanced ceramics, structural polymers and composites. The lecture is supported by exercises and practical experiments and uses material databases.
