Materials Science A
Objectives
The Curricular Unit intends to provide the basic knowledge of materials science and engineering, regarding its structure, properties, processes of obtention, testing, application and behavior. Its intends to achieve the understanding of the processing, nature and properties of the various classes of materials, stimulating in students critical thinking about how materials can be selected and designed for applications, taking into account the main challenges and sustainability issues.

Teaching method
The base concepts on the structure and properties of the diferent classes of materials are presented in the theoretical-practical classes so that they can be trated through exemples. These concepts are then consolidated through practical and laboratory works where the students complemente with additional exercices and perform practical sessions on the structural characterization of materials and determination of mechanical properties.
Evaluation method
1. Two (closed-booked) or final exam, accounting for 60% of the final grade.
2. Laboratory team work (groups of 4 students), including respective reports. If accounts for 50% of the practical part´s grade.
3. Resolution and analysis of exercides and case-studies in class. If accounts for 50% of the practical part´s grade. The practical part contributes with 40% to the overall grade.
