Materials Selection

Not applicable

In theoretical and theoretical-practical classes are presented the contents that allow the knowledge of the properties and applications of the studied materials, the manufacturing processes and methods of selection of materials. For this purpose, in theoretical-practical classes, commercial catalogs are often consulted, made the presentation of examples of materials in a wide range of materials gathered for the purpose, and also carried out some tests to determine mechanical properties. In the end, are presented different case studies of material selection for specific applications, taking into account the pre-requirements defined. 

Characterization of the major classes of engineering materials, making a comparison of metallic materials with polymers, ceramics and composites
Presentation of the properties of different types of materials. Examples of the application of these materials in the industry.
Description and application of methods for selecting materials.

Presentation and correlation of the main properties and parameters that characterize the materials
Quantification of properties. Correlation between function, material , form and process .
Selection of candidate materials and manufacturing processes.
Decision matrix for selection of materials. Analysis and selection of materials in case studies.

1- Assessment test I relating to component I (chapters 1 to 4), which will be carried out during the semester, after this component has been taught.

2- Assessment test II relating to component II (chapters 5 to 7), which will be carried out in any of the exam periods.

3- Group work carried out during the semester, which will be counted in any evaluation period of the corresponding academic year.

4- The final result of the evaluation will be weighted as follows:
Final grade = 60% exam I (max. 12 val.) + 20% exam II (max. 4 val.) + 20% group work (max. 4 val.)

5- Students who have not taken test I, as well as all others, can choose to take a complete test relating to components I and II during the exam period.

6- Students who take the full test (component I + Component II) in one of the exam periods, if they have completed group work, this will be counted in the final grade with a weighting of 20%. If they have not completed the group work, the final grade will only be counted by the exam test.
