Objectives

Mechanics Engineering is a multidisciplinary job with a vast scope.
According to a document written in 2004 by ASME (American Society of Mechanical Engineers) to meet the demands of the Biotech Century “mechanical engineers must assume a cooperate approach with a vast range, in which mechanics engineering methodology is a part of an industrial environment and multidisciplinary investigation”.

Basic scientific knowledge about materials and chemistry are crucial, as well as environmental concerns.

AIMS:
This course aims to acquaint students with:
-the materials used in mechanics engineering: metals, polymers, ceramics and composites;
- relationship between properties and chemical composition, chemical connections, structure, faults, processing and usage conditions
-material selection and its relationship with environmental and industrial issues
-science and human knowledge limitations
-basic notions of chemistry that are necessary to understand mechanics engineering phenomena (thermodynamics, corrosion, chemical reaction, etc)


Previous knowledge
Students are supposed to be acquainted with basic notions about atom, molecule and ion formation, as well as mass relationship in chemical reactions.

Learning Outcomes
By the end of the semester, students should:
- be acquainted with the different types of materials used in Mechanics Engineering, their properties and applications;
- be acquainted with mechanical(roughness, ductility, resistance), optical, thermal and electrical properties;
- understand and relate the various factors that contribute to the vast diversity of material properties (chemical composition, faults, chemical connections, processing, etc)
- be capable of relating remarks made in different occasions by different people and their interpretation, and their contribute to the knowledge of material and light formation;
- be capable of solving problems related with thermo chemistry, chemical kinetics and electrochemistry and associate everyday-life events with basic concepts of chemistry;
- know how to do a bibliographic research about materials and their application using different sources (books, articles, the internet, visits to companies and stores, interviews);
- have developed their ability to work in a group and to do oral and written presentations.

Practical classes (2h/per week)
These classes will be based on: a bibliography research assignment about materials/applications and oral presentation, exercises about mechanical properties of materials, atom structure and chemical connections. Visit to the laboratory of mechanical tests of DEMEGI, parts observation in different materials and tests on thermochemistry, kinetic chemistry and electrochemistry: problems solving.

Teaching methods and learning activities

This course is divided into theoretical-practical classes (two per week, they will last one hour, and they will take place in the auditorium for groups of about 70 students) and practical classes (one per week, they will last two hours and they will take place in the Materialography lab for 24 to 26 students).
This course will be based on: the presentation of concepts and basic knowledge regarding this course themes; theme discussion; presentation of typical materials and their applications; to carry tests on materials characterization in the lab and exercises.

Eligibility for exams

According to General Evaluation Rules of FEUP, students must attend to 75% of the theoretical-practical classes.

Calculation formula of final grade

Final Mark= bibliographic research assignment (report + poster + oral presentation) will worth 20% of the Final Mark + average grade of the 3 reports on laboratory tests, which will worth 15% of the Final Mark + grade of the final exam, which will worth 65% of the Final Mark.
Students will have to write a report on the laboratory tests that will be carried (3) one week after the test.
Students, who did not attend the laboratory test, will not be able to write a report on it. However, they can attend to other practical class that focus on the same theme.
Students who have a good presentation with a difficult theme can be awarded with one or two more values.

Examinations or Special Assignments

Not applicable

Special Assessment (TE, DA, …)
Students with a special status do not need to attend classes. However, students can attend to them and be assessed as ordinary students. If they do not, the Final Mark will only be based on the final exam. Other situations will have to be in concordance with General Evaluation Rules of FEUP.

Classification improvement

Students have to attend to another exam in the next year, if they want to improve their grade. However, if they want to improve their Distributed Classification grade, they have to do another bibliographic research assignment in the next year. The component of laboratory tests can not be improved.

Observations

The final exam will last two hours, and it is a closed book exam.
