1. Introduction
2. linear elasticity
3. classification of stresses
4. Failure due to plasticity
   • tensile test
   • dislocations
   • hardening mechanisms
   • guidelines for dimensioning
5. composite materials
6. fracture mechanics
   • hypotheses for failure
   • linear elasic fracture mechanics
   • crack resitance
   • experimental measurement of fracture toughness
   • defect measurement
   • crack propagation
   • application of fracture mechanics
   • atomistics of fracture

The student

• has the basic understanding of mechanical processes to explain the relationship between externally applied load and materials strength.
• can explain the foundation of linear elastic fracture mechanics and is able to determine if this concept can be applied to a failure by fracture.
• can decribe the main empirical materials models for deformation and fracture and can apply them.
• has the physical understanding to describe and explain phenomena of failure.

preliminary knowlegde in mathematics, mechanics and materials science recommended

regular attendance: 22,5 hours
self-study: 97,5 hours

The assessment consists of an oral examination (ca. 30 min) according to Section 4(2), 2 of the examination regulation.

• Engineering Materials, M. Ashby and D.R. Jones (2nd Edition, Butterworth-Heinemann, Oxford, 1998); sehr lesenswert, relativ einfach aber dennoch umfassend, verständlich
• Mechanical Behavior of Materials, Thomas H. Courtney (2nd Edition, McGraw Hill, Singapur); Klassiker zu den mechanischen Eigenschaften der Werkstoffe, umfangreich, gut
• Bruchvorgänge in metallischen Werkstoffen, D. Aurich (Werkstofftechnische Verlagsgesellschaft Karlsruhe), relativ einfach aber dennoch umfassender Überblick für metallische Werkstoffe

Übungstermine werden in der Vorlesung bekannt gegeben!

Die Veranstaltung wird letztmals im Wintersemester 2025/2026 angeboten!
