Materials Selection and Sustentability
The students should become aware of the importance of a Circular Economy of Materials by understanding the consequences
selecting materials for a given use.
Considering the wide variety of existing materials, this is only possible in a rational manner using a selection methodology that
systematically ranks materials and processing technologies using figures of merit.
By the end of this curricular unit, the student shall possess knowledge and skills allowing him to:
- Understand the Circular Economy of Materials concept;
- Be able to apply a Materials Selection methodology;
- Be able to perform a simplified Life Cycle Analysis of materials used for an application;
- Be able to interpret objectively the available data on a subject, even when incomplete, to make informed technical decisions;
- To know the implications of decisions taken in the field of Materials Engineering to relevant societal issues.

Two types of lessons will be considered: theoretical and practical.
Theoretical lessons will consist of lectures. Further treatment of the various topics will take place in the practical lessons, through the realization of debates. Also, computational work will be performed by students under the guidance of the teacher, corresponding to a sequence of case studies, using for the purpose the CES EduPack software, specifically designed to implement the Ashby selection methodology.
In parallel, the students will develop a project related to the topics in the curricular unit, to be presented by the end of the semester.
Minimum attendance conditions: 90% of the classes.
Continuous assessment: Test 1 (T1); Test 2 (T2); Project (P).
Conditions for exemption from final examination: ND ≥ 9.5 with ND = (T1 + T2 + P) / 3.
Final mark: N = ND or N = EF (if the student is not exempted from final examination).
