Methodologies |
Description | |
Assignments | Exercises will be proposed that students will solve outside the ordinary classroom, thus acquiring skills in the use of the necessary tools for problem solving. |
Problem solving, classroom exercises | The teacher will guide students in the application of theoretical concepts and results to problem solving, encouraging critical reasoning at all times. Exercises will be proposed and students will solve them, thus acquiring skills in the use of the necessary tools for problem solving. |
Tutorship of group | Practical and theoretical problems will be posed for the students and the teacher to solve together. |
Lecture | The lecturer will introduce, by means of theoretical explanations and illustrative examples, the concepts, results and methods of the subject. |

Assessment |
Description | Qualification | ||
Assignments | The continuous assessment system integrates the grading of the work presented by the students, taking into consideration the content, the presentation, the student's contributions and their alignment with the objectives. Attendance at the lectures is required in order to know the lines of action of the work proposed or practice requested. | 20% | |
Mixed tests | These will be oriented towards the qualification of theoretical and theoretical-practical concepts and the skills acquired for their application. This evaluation is articulated through written exams carried out on dates agreed with the students. | 80% | |
Other comments and second call | |||
In order to pass the course, a minimum grade of 3.5 points must be obtained in the final exam of the whole course. The course is passed if the final evaluation is equal to or higher than 5 points. The proposals and competences worked on individually and in groups, with and without the teacher, will also be assessed. In the second call, the results of the tests obtained throughout the semester are valid, although it is not compulsory to have taken them. In the case of not taking the partial tests or individual work, the mark for the final exam will be 100% of the evaluation. |

- CANET, J. M., Cálculo de Estructuras, book 1.Fundamentos y estudio de secciones, Ediciones UPC, 2000. Basic book for RESISTENCE OF MATERIALS Excellent book on Strength of Materials with a syllabus very similar to the 2nd year course. It presents a brief introduction to Elasticity, sufficient to subsequently develop the study and calculation of bar sections. It presents some problems solved in each topic as well as a larger collection of proposed problems. - FERNÁNDEZ DÍAZ-MUNIO, R., Breviario de Elasticidad, E.T.S. de Ingenieros de Caminos, Canales y Puertos de Madrid, (1996). This book is a must for anyone who wants to make a first study of the Theory of Elasticity without getting bored. It explains in a light-hearted tone the fundamental concepts and approaches to solving the elastic problem. Its inclusion among these references is not due to its jokes and diverse quotations, but rather to the fact that among them there is a remarkable work of synthesis and clarity of ideas. Although the course does not plan to go into much of the aspects of the Theory of Elasticity in depth, this reference is recommended reading for the clarity of ideas that it can provide, especially with regard to the ways of solving the elastic problem. - GARRIDO, J.A. and FOCES, A., Resistencia de Materiales, University of Valladolid, (1999). Recommended book for RESISTANCE OF MATERIALS. Excellent book for the study of Strength of Materials. The one-dimensional model of members is developed in a clear and concise way and the calculation of stresses in the section is explained, maintaining at all times the parallelism and the connection between Strength of Materials and Elasticity. This book is recommended for its precision in the treatment of stress calculation, although some of the topics it deals with are outside the scope of the course, such as the introduction to the Direct Method of Stiffness or Torsion in buckling problems. In all the topics there is an example to clarify the preceding theoretical development. The joint treatment given in the study of tension (compression)-bending implies a greater degree of complexity at the beginning, but at the end it is an advantage in terms of clarity of ideas. - VÁZQUEZ, M., Resistencia de Materiales, Universidad Politécnica de Madrid, (1986) Recommended book of RESISTENCIA DE MATERIALES. Excellent textbook by the Professor of the subject at the E.U.I.T. de Obras Públicas, which is not only aimed at his students but is intended to be more general and its use is very interesting for other students or professionals. In the first three chapters it deals with the basic topics of Elasticity (stresses, deformations and their relationship) necessary for the study of Strength of Materials. Subsequently, it deals with practically all the lessons of the programme (axial, shear, bending and torsional forces, both in their isostatic and isostatic cases). |

- ARGÜELLES ÁLVAREZ, R., Cálculo de Estructuras, E.T.S.I. Montes de Madrid, (1981). This work is structured in two volumes, the first of which is devoted to Elasticity, Strength of Materials and Calculation of Structures, and the second to special topics. In turn, the first volume can be broken down into a part dedicated to Elasticity, suitable for the level at which it is dealt with in the programme, and a second part on Strength of Materials and Calculation of Structures, which is perfectly suited for seminars and specific work or for consultations on special topics, which are dealt with within the subject. The advantages of the book are its good generalised theoretical treatment and the fact that it is written by an author with several texts on these subjects, giving a globalised vision; the disadvantages are that the theoretical exposition requires a high level of mathematical knowledge and, at times, its generality makes it lose its physical sense. - ORTIZ BERROCAL, L., Resistencia de Materiales, McGraw-Hill, (1991) This text, together with the previous one, completes the course on Elasticity and Strength of Materials. It presents practically all the topics in the syllabus, carrying out a systematic analysis of the actions deriving from an external stress (axial forces, shear forces, bending moment and torsional moment; as well as composite stresses), both for isostatic and hyperstatic structures, and ends with the important topic of instabilities (buckling). At the end of each chapter, typical problems are proposed and solved. - TIMOSHENKO, S., Resistencia de materiales, Espasa Calpe, S.A. Madrid, (1982). It is a work consisting of two volumes. The first one has a content adapted to the level of an engineering school and the second one is written as the author himself says "for advanced students and research engineers or designers". Thus, the first volume can be considered as basic for the development of the programme and the second as a reference volume for the development of works and seminars. It goes without saying that Stephan Timoshenko has played an important role in the development and advancement of this and related subjects. These are texts that have been widely used and it seems obligatory to continue recommending them, as they have, among other advantages, their concreteness and conceptual depth, with problem solving at the end of each question explained. Among its disadvantages we can point out its difficulty and small differences in nomenclature with respect to that followed during the course (fatigue-tensions). - TIMOSHENKO, S. and GOODIER, J.M., Theory of Elasticity, Urmo, (1975). Another book by the great American specialist of Russian origin, written this time in collaboration, constituting a broad and complete treatise, which is perhaps too high for this level, with many of its chapters being usable both within the theoretical programme and for monographic works and seminars. |
