• Part 1: It will deal with the vibration concepts most applicable in industry.
• Part 2: This block will focus on fracture mechanics, an advanced approach to assessing structural integrity.
• Part3: Advanced methods of fatigue analysis and monitoring of fatigue-generated defects.

Link with the SDGs (SustainableDevelopment Goals):

• SDG 9. Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation. Promoting the use of new technologies and the efficient use of resources, by studying the structural requirements of a system.
• SDG 11. Make cities and human settlements inclusive, safe, resilient and sustainable. Developing materials and properties that enable the implementation of quality infrastructures.
• SDG 12. Ensure sustainable consumption and production patterns. Correctly dimensioning structural elements and optimising the amount of resources used based on an in-depth knowledge of the behaviour of the materials used.

The course will be developed through lectures and exposure of general examples (M1 - Lectures, M2 - Exposure of theory and general examples and M3 - Introductory activities and problem solving).

With a total of 45 classroom hours and an estimated 90 hours of autonomous work by the student, in these classes the competences CEM2, CEM4, CEM9 will be developed.

The methodology used to teach the concepts of the subject that allow the development of these competences will be presented through multimedia presentations, theoretical expositions and examples.

Practical: Certain content will be explored through activities that involve the practical application of knowledge (M11 - Exercise resolution and M6 - Practical activities). This will develop the competences CEM2, CEM4, CEM9 and also CT4 through the use of computer equipment.

Collective tutorials. This activity is organised in short seminars where, by means of problems, some of the subjects studied in the lectures will be studied in depth, and students' doubts will also be solved.

Seminars. A seminar/visit will be organised on some of the topics related to the context in which the subject is developed.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

The grading system will be based on RD 1125/2003 of 5 September, which establishes the European credit system and the grading system for official university degrees.

For the evaluation of the subject, an exam will be the main evaluation procedure (55% of the final grade of the subject) with which the competences CEM2, CEM4 and CEM9 and Outcomes 20, 21 and 22 will be evaluated. However, in order to encourage and reward continuous work throughout the subject, other evaluation criteria have been taken into account such as attendance and participation in class, laboratory practice reports (which will allow the evaluation of the competence CT4 in addition to the above) and delivery of activities proposed by the teacher.

As far as the exam is concerned, students must obtain a minimum mark of four out of ten in order to pass the course. It should be added that attendance at the practicals, as well as the delivery of the practical reports, is compulsory. Additionally, it is necessary to obtain a minimum of 3 points out of 10 in each of the internship reports submitted. Failure  in the practical reports on the dates set by the teacher will mean failing the course.

Institution in charge of data processing: Universidad de Jaén, Campus Las Lagunillas, s/n, 23071 Jaén

Data Protection Delegate: dpo@ujaen.es

Purpose: In accordance with the Universities Law and other national and regional regulations in force, carrying out exams and assessment tests corresponding to the courses students are registered in. In order to avoid frauds while sitting the exam, the exam will be answered using a videoconference system, being able the academic staff of the University of Jaén to compare and contrast the image of the person who is answering the exam with the student's photographic files. Likewise, in order to provide the exam with evidential content for revisions or claims, in accordance with current regulation frameworks, the exam will be recorded and stored.

Legitimacy: compliance with legal obligations (Universities Law) and other national and regional regulations currently in force.

Addressees: service providers who are the owners of the platforms where the exams are carried out and with whom the University of Jaén has signed the corresponding data access contracts.

Storage periods: those established in current in force regulations. In the specific case of exam videoconference recordings, not before the examination records and transcripts are closed or the exam can still be reviewed or challenged.

Rights: you can exercise your right of access, amendment, cancellation, opposition, suppression, limitation and portability by sending a letter to the postal or electronic address indicated above. In the event that you consider that your rights have been violated, you may submit a complaint to the Andalusian Council for Transparency and Data Protection www.ctpdandalucia.es
