The course includes subjects to acquire the basic knowledge of materials science. Common to other engineering studies in Europe that can homologate to this engineering degree, the course contains subjects including the growing importance of engineering materials, the basic structure of the different classes of materials (metals, ceramics, polymers), the transformations that have or may have taken place in their manufacturing and in service, as well as their mechanical, electrical, electronic, magnetic, thermal and optical properties. The course finishes with a brief description of the main features of the materials most commonly used among the three previously mentioned families, and by presenting the usual criteria in their selection for final uses.



Being located within a basic module, the course allows an initiation in the field of science and engineering of materials. It will also lead to generate in the future graduates the wish to complete their knowledge on materials from novel aspects that concern industrial engineering as a profession.



Mechanisms to ensure horizontal coordination within the course are based on the programmed coordination of this subject with others that introduce and employ similar concepts and principles, e. g. Static-Mechanics and Thermodynamics.



The mechanisms assuring vertical coordination are related to the structure of the planning itself of the undergraduate degree in Industrial Engineering, hence subjects necessary for the monitoring of materials are already studied previously (Physics and Chemistry), while subjects that need of this course are programmed for later on.

The subject is evaluated through continuous evaluation. In both cases, the final note of the subject will take into account the evaluation of the competencies and learning results in each of the teaching modalities of the subject according to the following criteria:

75% written exam related to theoretical classes and classroom practices;

15% related to seminars;

10% related to laboratory practices.

To pass the subject you must get a 5/10 in each of these three parts.

Students have the right to waive the continuous assessment and opt for the assessment according to one single final assessment test. The students who choose this option must inform the lecturer before week 9th.

If, due to circumstances, the University is unable to organize the evaluation tests at the university, the changes relevant to the online evaluation will be made. In that case, the characteristics of the online evaluation will be published and communicated by eGela.

CONTINUOUS EVALUATION:

Written exam:

It consists of a theoretical part and a practical part. Both have the same weight in the exam score. The theoretical part will consist of test questions and short questions, in which the concepts of the subject will be developed. The practical part will consist of two problems to be solved. Marks of both parts must be compensated and the estimate is at the discretion of the professor. On the day of the written exam, only writing tools, ruler, square and calculator may be available.

Laboratory practice:

There are three laboratory practices. The evaluation of each practice will be carried out using an e-Gela test, which will be carried out according to established deadlines. The final practice note will be calculated by applying the arithmetic average of the three individual practices. However, to be able to perform the practice it will be necessary to have successfully completed a test prior to it through e-Gela. To do this, it is necessary to correctly answer 3 of the 5 questions of the previous test. People who do not perform or do not pass the test will not be able to perform the practice or answer the practice evaluation test and, therefore, the note corresponding to this practice will be zero. Likewise, even having attended the practice, not answering the questions of the corresponding test within the established deadlines will be zero. We understood, that students who do not attend any of the laboratory practices refuse to be evaluated by continuous evaluation, so they will be evaluated by the final evaluation system.

*Students who, having attended the laboratory practices, do not achieve the minimum mark in the continuous evaluation criteria, will have the option of being evaluated by a theoretical/practical question on the day of the final exam.

*If you do not pass the subject, the practice note is not kept for the next course.

Seminars:

Each seminar is associated with an individual task that the students should perform and deliver on the corresponding dates. The final note to the seminars will be calculated as the arithmetic mean of the notes to these tasks. In the second and third seminars (Item 7: Corrosion), in addition to the tasks to be performed, a 5-question test in E-Gela is included, which must be answered prior to the relevant seminar session, and the note obtained will weigh the note of the task.

Even having attended the seminar, not handing over the corresponding task within the deadlines will be zero. Students who do not attend the seminar will not be able to give the corresponding task and consequently the corresponding note will be zero. If the student does not attend any of the seminars, we understand that he/she refuses to be evaluated by continuous evaluation, so he/she will be evaluated by the final evaluation system.

*Students who have attended the seminars and do not achieve the minimum mark in the continuous evaluation criteria will have the option of being evaluated by a theoretical/practical question on the day of the final exam.

*If you do not pass the subject, the seminar note is not kept for the next course.



FINAL EVALUATION

The final evaluation system will be carried out through a final written exam consisting of the same three parts as the continuous evaluation, with the same weighting, criteria and requirements to approve the subject: a written examination related to theoretical classes and classroom practices whose weighting is 75%, 15% related to seminars and 10% related to laboratory practices. A 5/10 note must be obtained to pass each of the three parts.
