Academic Year 2023/2024 - Teacher: Giovanna FARGIONE

Expected Learning Outcomes

The lessons will be held three-weekly in the second half of the second year, also the calculation and project exercises will be carried out.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

Learning assessment may also be carried out on line, should the conditions require it.

Required Prerequisites



Attendance of Lessons

The lessons will take place three weeks in the second semester of the second year, calculation and project exercises will also be carried out biweekly.

Learning Assessment

Learning Assessment Procedures

A test  for each module of the course

Open-ended and multiple-choice questions

For those who do not do the tests on the road, the oral examination on the contents of the course and the project performed is provided

One CAD  project 

In the case of oral exam. Elements to be evaluated: relevance of the answers, quality of their contents, ability to connect with other topics within the program, ability to report examples, quality of technical language, and overall expressive ability.

To guarantee equal opportunities and in compliance with current laws, students can request a meeting in order to plan any compensatory and/or dispensatory measure, according to the educational goals and specific needs. In this case, it is advisable to contact the CInAP (Centre for Active and Participated Integration - Services for Disabilities and/or SLD) professor of the Department where the Degree Course is included

Examples of frequently asked questions and / or exercises

1)Calculation for valve design

2) calculation of a particular type of valve; 

3) CND typologies (NDT); 

4) corrosion methodologies; 

5) fatigue phenomena in welding;

6) welded joints.
