Based on the fundamental knowledge of Materials Science, acquired in the second year, this course contributes to deepen the knowledge about the properties and behavior of structural materials, understood as those materials that are used to produce components subjected to different mechanical demands, both in machinery and in structures. This course will be of general interest for several engineering disciplines and branches, including the completion of the final degree projects on Industrial Engineering.



The first part of the course delves into the nature, properties and processing of structural materials, with special focus on the relationship between the mechanical behavior, the microstructure and the processing conditions of metallic materials. The relevant aspects related to the use of polymeric, composite and ceramic materials for structural functions are also approached. On the second part, the course immerses into the study of failure mechanisms in service conditions, including the bases of Linear Elastic Fracture Mechanics and its use in design and product engineering, the fundamentals of the Elastic-Plastic Fracture Mechanics, the application of both disciplines in the analysis and forecasting of fatigue and stress corrosion failure, as well as the fundamentals of creep (plastic) failure of materials at high temperatures.



The curriculum for the degree integrates this course with the rest of the courses considering the expertise and skills that the students should exhibit to approach it, and those which the course aims to provide. Vertically, it has been implemented in the 4th year, coordinated with various courses from previous years where the students acquire the expertise and skills required as a starting point for this course. The horizontal coordination of the course with other courses settled on the 4th year of the degree renders a reasonable activities-schedule for the students and also includes the coordination of the contents with several other courses, which introduce and use similar concepts and principles, such as the courses on Machine Elements, Calculation of Machines and Theory of Structures.

The course employs four teaching modalities: lectures, exercise-classes, seminars and laboratory practices.



In practice, the lectures and exercise-classes take place in joint sessions where extensive explanations will be given by the teacher and, examples and exercises, will be approached together with the students. The documents to study the syllabus and to approach the exercises are available in eGela, as well as in the reprography service of the EIB. eGela will also include the activities and tasks scheduled as non-classroom work for the students, as well as other additional material suitable to approach the course.



The seminars will focus on specific topics, where students will advance their expertise by means of teamwork and occasional debates around case studies. In this way, the syllabus-contents about those topics is attained in a practical and applied way.



In the laboratory practices, a small team project will be developed. It entails experimental work in the metallurgy-laboratory in order to acquire knowledge and expertise about experimental techniques, as well as analysis and decision-making skills.



In the event that minimum distances between students are established for health-safety reasons, the practices will be organized on a delegated basis and, likewise the rest of the teaching modalities, the conditions indicated by the EIB management team will apply. Also, in the event that face-to-face assessment cannot be carried out, the pertinent changes will be made to carry out an online evaluation by using the existing computer tools at the UPV/EHU. The characteristics of this online evaluation will be published in eGela.

• Continuous Assessment System
• Final Assessment System
• Tools and qualification percentages:
  • Written test to be taken (%): 45
  • Realization of Practical Work (exercises, cases or problems) (%): 20
  • Team projects (problem solving, project design)) (%): 25
  • PRACTICAS DE LABORATORIO (%): 10

A continuous assessment methodology will be used, with several activities and tasks. The weighting will be as follows:



-Final assessment test, including exercises and theoretical questions: 45% of the final grade.



Syllabus content comprehension and expertise in solving practical exercises. Assessment of the skills for autonomous work.



- Completion of various tasks and activities throughout the course: 20% of the final grade. Achievement degree of several syllabus topics (theoretical background and practical exercises).



- Written reports, poster presentations and oral communication of the work carried out in the Seminars: 25% final grade.



Assessment of the skills and expertise to use theoretical and practical knowledge to solve open problems and case studies.



Assessment of the skills and expertise for teamwork by presenting proposals, analyzing other members´contributions, discussing ideas and executing pertinent actions. Interpersonal skills.



-Writing a report and a visual presentation about the Laboratory project, and presenting it face to face to the class: 10% of the final grade.



Assessment of the skills to approach a poorly defined task, which needs to develop a plan for the required steps, to execute them experimentally, to analyze critically the obtained results, to propose solutions and to communicate them, both in writing and orally. All of it as part of a team.



It is compulsory to carry out all the tasks, tests and activities scheduled in the continuous evaluation. A score above 5 out of 10 must be obtained in each of them. Exceptionally, students may pass with a Final assessment test score higher than 4.5 out of 10, as long as the rest of the activities and tests evaluated in the course have a grade higher than 5 out of 10.



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 teacher before week 12th. In this case, the final test will contain questions and exercises regarding all the topics and aspects approached along the course in all the teaching modalities.



The students have the right to revoke the assessment of the current course. No notification to the teacher is required in that case. By default, any student who does not take the final assessment test revokes the assessment of the course.

A final assessment test will be held for 100% of the final mark. It will contain questions and exercises questions and exercises regarding all the topics and aspects approached along the course in all the teaching modalities.



Students who, having done continuous assessment during the ordinary assessment period, passed all the assessed activities except for the final assessment test, may choose to keep the grade obtained in those activities. In that case, a final assessment test in the extraordinary call will be 45% of the final grade, as long as the minimum grade obtained in it is 4 out of 10.



By default, the students who do not take this final assessment test revoke the assessment of the course.
