Objectives

The curricular unit intends to perform an unifying role for the body of knowledge acquired by the student throughout the course, stimulating the building of a relational approach to the different classes of materials, through a comparative insight of their structures, properties and behaviours, within bounds set by technological, economic and environmental limitations.
During the UC, the student must come to dominate the relationships within the structure- properties-processing triangle, and become able to translate them into the selection process of a material for a given application, taking into account the pertaining environmental and cost factors. To do so, he/she will become proefficient with the Ashby selection methodology, and in the process will internalize behaviours related to time management and scheduling, information research and initiative.

Subject matter

Teaching method

The theorectical lectures are of expositive nature, supported by projection of slides, with resolution of some illustrative exercices.

The practical lectures are used for small project resolution within the Materials Selection scope, using mostly the software EduPack.

Tutorial support offered during development of a final Materials Selection project by the student.

Evaluation method

Attendance conditions:

- Minimum classification of the Individual Report and its discussion: 10.

- Minimum Lecture Attendance: 60% of the practical sessions.

Continuous assessment:

Part 1 (8 weeks)

- Test 1 (T1)

- Individual Report (TI)

- Discussion of Individual Report (DTI)

Part 2 (6 weeks)

- Test 2 (T2)

Conditions for exemption from final examination: ND ≥ 9,5

with ND = 0,6 × (T1 + T2) + 0,25 × TI + 0,15 × DTI

Final classification (NF):

- If exempt from examination:

NF = ND

- If not exempt from examination:*:

NF = 0,6 NE + 0,25 × TI + 0,15 × DTI

* Provided that the minimum score obtained in the examination, NE ≥ 9,5. Otherwise, NF=NE.
