Abstract

The course provides an introduction to the concepts of fracture mechanics and covers theoretical concepts as well as the basics of experimental 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.

Objective

To acquire the basic concepts of fracture mechanics in theory and experiments, and to be able to apply them to the solution of relevant problems.

Content

1. Introduction: damage and fracture mechanisms, stress concentrations, 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. Overview of additional topics: fatigue, dynamic fracture. Lectures are complemented by experiments in the lecture hall, exercise classes and one laboratory session.

written 90 minutes
Aids
One double-sided hand-written page of notes/formulae and a calculator are allowed. No further material is allowed.
The written final exam covers all contents of this course, including lectures and exercises. It counts 70% towards the final grade.Additionally, there will be a compulsory continuous performance assessment in the form of five homeworks to be discussed and assigned during the course of the semester. The homeworks will count 30% towards the final grade (6% each). They are integrated with the lectures and exercises and require the student to understand and apply the course material.
