Syllabus
Prerequisites: Bases of Machine Design (beam theory, strength criteria, fatigue design of mechanical components) and bases of mathematics (solution of ordinary differential equations, integrals).
Target skills and knowledge: 1. Introduction to the finite element method (statics and dynamics)
2. Design of welded joints against static and fatigue loadings
3.Design of bolted joints against static loadings
4. Bending critical speeds
5. Euler load and buckling
Pressure vessels
Examination methods: Written exam, divided into two parts:
- 2 or 3 application exercises (for a total score of 10 points out of 30)
- 5 open questions (for a total score of 20 points out of 30).
The oral exam is optional and possible only for scores over 25 (oral interview with 2 or 3 open questions).
Assessment criteria: The evaluation criteria will be:
- Completeness of the theoretical knowledge acquired on the topics of the course
- Ability to apply the theoretical knowledge to the practical design of mechanical components
Course unit contents: The specific contents of the course can be summarized in the following points:

1. Finite element method: Introduction to the method, stiffness matrices of trusses and beams in local and global reference systems, assemblying of stiffness matrices, stiffness matrices for solid elements, modal analysis of structures and plates. Application examples, with the practical finite element analysis of some mechanical components (a plate with a hole, transmission shafts, three-dimensional structures)

2. Static and fatigue design of welded joints: Classification of weld beads, static design criteria, examples of application. Fatigue curves for the fatigue design of welded joints. Equivalent stress and rain flow method.

3. Static and fatigue design of bolted joints: Classification of bolted joints and verification criteria for normal and high-strength bolts.

4. Critical speeds of shafts. Introduction to the problem and calculation methods (track method, Durkerley method). Examples of application.

5. Elastic Buckling. Euler formula. Practical aspects and competition between instability analysis and resistance analysis. Standards, and examples of application.

6. Design of thin-walled, thick-walled vessels: Basic theory and practical examples (tanks, flywheels, turbine discs, etc.)
Planned learning activities and teaching methods: Theory lectures in the classroom and numerical exercises with the aid of a commercial numerical code (ANSYS).
Additional notes about suggested reading: Personal notes and written notes, including all the topics and exercises with solutions provided by the professor.
