B019083 - COMPLEMENTS OF MACHINE DESIGN

Italian

The objective of the Course is to give further information about the mechanical behaviour of materials, in the perspective of designing and verifying mechanical structures.

- T. L. Anderson, Fracture Mechanics: Fundamentals and Applications, Taylor and Francis.
- G. E. Dieter, Mechanical Metallurgy, McGraw-Hill.
- D. Broek, Elementary Engineering Fracture Mechanics, Nijhoff.

- Acquire notions about the mechanical behaviour of metals and other materials; learn analysis and design procedures that allow for the different failure mechanisms.
- Acquire the capability to analise a mechanical system in order to apply the most suitable design approach, as well as the ability to understand the reasons of the failure of a mechanical component with the aim to suggest corrections (failure analysis).
- Use of standard procedures for design and verification. Capability to obtain, by means of experimentation or literature (also using technical norms), material's data.

Basic notions about Mechanics of Materials and Machine Design.

Frontal lessons.

Oral examination. During the test the following arguments will be checked:
- Theoretical knowledge about the mechanical behaviour of materials, particularly as regards fatigue, fracture mechanics and other failure modes.
- Knowledge of the different design approaches (design for fatigue, damage tolerant design, etc.).
- Capability to chose a material suitable for the different applications.
- Capability to identify the most common causes of failure and to suggest countermeasures.
- Capability to understand experimental techniques and standard regulations.
