| Kurzbeschreibung | The course provides an introduction to the concepts of fracture mechanics and covers theoretical concepts as well as the basics of experimental and computational methods. Both linear and non-linear fracture mechanics are covered, adopting the stress and the energetic viewpoints. A basic overview of fatigue and dynamic fracture is also given. | ||||
| Lernziel | To acquire the basic concepts of fracture mechanics in theory, numerics and experiments, and to be able to apply them to the solution of relevant problems in solid and structural mechanics. | ||||
| Inhalt | 1. Introduction: damage and fracture mechanisms, brittle and ductile fracture, stress concentrations, weak and strong singularities. 2. Linear elastic fracture mechanics: the stress approach, the energy approach, mixed-mode fracture, size effects. 3. Elasto-plastic fracture mechanics: small-scale yielding, crack tip opening displacement, J integral. 4. Basics of experimental methods in fracture mechanics. 5. Basics of computational methods in fracture mechanics: finite element techniques, cohesive zone models, phase field modeling. 6. Overview of additional topics: fatigue, dynamic fracture, environmental cracking. | ||||
| Skript | Lecture notes will be provided. However, students are encouraged to take their own notes. | ||||
| Voraussetzungen / Besonderes | Mechanics 1, 2, and Dynamics. | ||||
