Objectives

The main objective of this CU is to provide students with the fundamental concepts of material selection. The seven topics of the programmatic content constitute a natural sequence of presentation of the concepts.

Chapter 1 will give the student a historical overview of the evolution of material use.

Chapter 2 will allow the student to know the concept and alternate types of design. Get to know the design tools.

Chapter 3 will allow the student to know the material databases.

Chapters 4, 5, 6 and 7 will allow the student to interpret tables and material property charts, establish the functional requirements of a component to select materials according to their application, select materials according to the manufacturing process selected, the design of the component to the manufacturing process and finally establish the relationship between the function of the component, the material, the geometry of the component and the processing.

Learning outcomes and competences

1. Know the concept and alternative types of design. Know the design tools and materials databases.


2. To know the methodologies of selection of materials in the scope of the design in mechanical engineering


3. Know how to interpret tables and charts characterizing the mechanical behavior of materials


4. Know how to establish the functional requirements of a component


5. Know how to select materials based on your application


6. Know how to select materials according to the selected manufacturing process


7. Know how to adapt the design of the component to the manufacturing process


8. 8. Know how to establish the relationship between component function, material, component geometry and processing.


9. Know how to use material selection software


10. Working in groups and acquiring greater competence in communication strategies (written and oral) and motivation

Teaching methods and learning activities

Theoretical concepts will be presented in theoretical-practical classes. In these classes will also be proposed simple study cases that will allow to consolidate the presented concepts. Part of these theoretical classes will be aimed at theoretical presentations made by students.
The practical laboratory classes will be devoted to the discussion of the study cases proposed in the theoretical classes and also the follow-up of the two works that students will carry out for evaluation throughout the semester. These two group work will present different degrees of difficulty. The first will serve to consolidate the basic concepts, the second will be an integrative work of all the concepts associated with the selection of materials. This second paper will be the subject of an oral presentation.

Eligibility for exams

Article 4 of the General Evaluation Standards

Calculation formula of final grade

Calculation formula of the final classification:
CF = A * 0.3 + B * 0.4 + C * 0.2  + D * 0.05
CF - Final classification
A- Classification of the exam
B- Classification of group work (report + presentation)
C- Classification of theoretical presentation
D- Average of the ratings of the formative questionnaires performed in the theoretical classes.

Special assessment (TE, DA, ...)

Examination on all subjects and activities carried out within the scope of the discipline. Realization, presentation and defense of a work on a subject addressed in the discipline (2 weeks of delivery time) CF = A * 0.6 + B * 0.4 CF- Final classification A- Exam classification B- Classification of the work
