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
