Sustainability and Materials Selection
It is intended that students acquire the ability to choose what is the best material for a given application.
Considering the wide variety of existing materials, this is only possible in a rational manner using a selection methodology that systematically elenque materials by figures of merit (material indexes). Also, the selection methods for material processing, shaping and joining may have the same approach.
The methodology is supported by a specific software working with a database of material properties.

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.
Minimum attendance conditions: 90% of the classes.
Continuous assessment: Test 1 (T1); Test 2 (T2).
Conditions for exemption from final examination: ND ≥ 9.5 with ND = (T1 + T2) / 2.
Final mark: N = ND or N = EF (if the student is not exempted from final examination).
Material and process selection, attending to design, performance, cost and environmental constraints.
Databases for materials selection.
Graphic representation of properties as a basis for a selection strategy: Ashby’s selection system.
