Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)

The overall objective of the unit is to provide general knowledge of materials used in engineering applications, their structure and typical properties, and their processing and recycling methods. Specific objectives to achieve are:
- To know metallic materials and their properties, with relevance to ferrous and aluminium alloys.
- To know ceramic materials, both technical and traditional, and their typical properties; to know sintering and vitrification phenomena and to relate them with ceramic and glass properties.
- To know polymeric materials and their typical properties, production and processing techniques, recognizing the effect of processing additives on attained properties.
- To know composite materials, with relevance to fibre reinforced polymers.
- To thoroughly know dedicated recycling processes for each family of materials, including their advantages and limitations and typical properties, markets and common applications of the resulting secondary materials.

Teaching methodologies

Theoretical-practical classes with:
- Presentation of concepts and correlation between different types of materials
- Case studies and examples of typical materials, applications and recycling methodology
- Problem solving

Consolidation of concepts in laboratory classes

Contact with the Portuguese recycling industry through field trips and seminars

Assessment methodologies and evidences

HYPOTHESIS 1
Distributed assessment, without final examination

- Intermediate tests (3 tests) - 70%
- Lab work (4 works with report delivery) - 25%
- Field trips and/or seminars (mandatory delivery of 2 reports) - 5%

It is mandatory to submit to both tests.
Failure to submit one of the other evaluation elements implies a "zero" score in that element.
Tests do not demand minimum score; the average score in the tests has to exceed 9/20.
Approval in the course demands final grade higher than 9.5/20.
Assistance to at least 70% of the TP classes is required.

or
HYPOTHESIS 2
Assessment with final examination

- Final examination - 75%
- Lab work (4 reports) - 25%
Failure to submit one of the reports implies "zero" score in the corresponding work
Attaining approval in the course implies an exam score grade higher than 9.5/20 and an average score higher than 9.5/20

Observations

1. All information on the course is available at the "Contents" area in SI.

2. All tests and exams are carried out without consultation.

3. It is mandatory to take the Laboratory Guide to the corresponding laboratory class. The Guide should be read before class.

4. The use of mobile phones in the classroom and laboratory is strictly forbiden.
