Syllabus Information

1. General information

The objective of the subject is to enable the student to analyze and design the simplest and also the simplest deformable solid and design the simplest and most common deformable solid, the the bar element, which appears in most of the building structures as well as in innumerable machine elements.

Therealization of practical sessions allows to check the validity of the basic hypotheses and the different simplifications of the different theoretical concepts developed and, on the other hand, the classes of problems and practical cases allow to demonstrate the application of these concepts. These activities proposed during the development of the course not only seek this assimilation of concepts, but also the enhancement of reasoning, synthesis, resolution and subsequent analysis of the results of different problems.

These approaches and objectives are aligned with some of the Sustainable Development Goals, SDGs, of the 2030 Agenda (https://www.un.org/sustainabledevelopment/es/) and certain specific goals, in such a way that the acquisition of the learning results of the subject provides training and competence to the student to contribute to some extent to their achievement:

SDG 9. Industry, innovationand infrastructures.

9.4 By 2030, upgrade infrastructure and convert industries to be sustainable, using resources more efficiently and promoting the adoption of clean and environmentally sound technologies andindustrial processes , with all countries taking action in accordance with their respective capacities.

2. Learning results

The student, in order to pass this subject, will have tó demonstrate that:

Understand the concepts of stress and deformation and know how to relate them by means of the behavioral equations, to solve simple three-dimensional elastic solid problems.

Know how to calculate and represent stress diagrams in bars and simple structures.

Know how to solve torsion problems in axes and simple three-dimensional structures.

Know how to solve composite bending problems in beams and simple structures.

To understand the concepts of plasticization depletion and rupture, and to be able to correctly apply the most common plasticization criteria.

Understand the phenomenon of bar buckling and knows how to solve isolated bar buckling problems.

Know how to distinguish between isostatic and hyperstatic problems and knows different strategies for solving the latter .

Identify the social, environmental, economic and industrial implications of strength of materials problems.

4. Academic activities

Theoretical classes The content of the program is developed and examples of application are presented. For the definition of technical terms, both Spanish and English are used simultaneously.

Problem classes (T2). Problem solving to complement the theoretical classes.

Simulation and laboratory practices: The practical sessions are intended to familiarize students withcomputationalsimulation throughdifferent applications.

Subject Work (T6). Development of project-based learning through teamwork.

Tutoring. Resolution of doubts in a personalized way or in small groups.

5. Assessment system

There are two assessment modalitiesto pass the subject: gradual and global.

The following tests are proposed for agradual assessment:

Subject work (15 %)

• The following will be proposed́ a work related to the contents of the subject that involves the analytical and numerical resolution of a bar structure.
• Its assessment will be based on the written report submitted and its oral defense.
• A grade equal to or higher than 4 will allow averaging with the rest of the activities.

Practices (20 %)

• It will be carried out in five sessions of 3 hours of individual computer practice.
• Its assessment will be based on questionnaires filled out by the students in the ADD.
• A grade equal to or higher than 4 will allow averaging with the rest of the activities.

Examination (65 %)

• An intermediate control evaluating the basic contents of the subject (15 %) will becarried out. Agrade of 4 or highermust be obtained to average with the rest of the activities.
• Final exam during the period set by the School (50%). You must́ obtain a grade equal to or higher than 4.0 to mediate with the rest of the activities.

For anoverall evaluation of the course, the following is proposed:

Final exam. It will consist́ of a theory/problem part (85%) and a practical part (15%), having to reach aminimumscoreof 5 in each part.
