General description The mechanics of materials is a basic concept in engineering that must be understood by all students who wish to acquire competences in the resistance and physical performance of structures, whether natural or man-made. This semester includes fundamental concepts such as stresses, deformations and displacements produced by different types of stresses. Concepts such as strain energy are also introduced.

Learning aims
Competences
Students have demonstrated knowledge and understanding in an area of study that builds on the foundation of general secondary education, and is usually at a level that, while relying on advanced textbooks, also includes some aspects that involve knowledge from the cutting edge of their field of study. Students are able to convey information, ideas, problems and solutions to both specialist and non-specialist audiences. C1
C4
Knowledge and use of the principles of mechanics of materials. A17512

Methodologies
Methodologies   ::  
  Description
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.
Personal tuition Doubts will be solved individually for each student.
Lecture Theoretical classes where the theoretical bases of the subject will be explained, reasoned and deduced. At the end of each section, simple exercises will be solved to clarify the theory explained.

Personalized attention
 
Personal tuition
Description
All students requesting both face-to-face and distance tutoring will be attended to.

Assessment
  Description Qualification
Mixed tests There shall be three types of written tests:
1. Final exam of the whole course
2. Partial exam
3. Individual work and/or periodical controls to be carried out by the student.

1: 70 %
2: 20 %
3: 10 %
 
Other comments and second call

In order to pass the course, a grade of at least 3.5 out of 10 must be obtained in test 1 (final exam of the whole course). The course is passed if the final grade 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. of Public Works, 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 topics in the programme (axial, shear, bending and torsional forces, both in isostatic and hyperstatic cases, the phenomena of instability and the energy theorems), which makes it particularly recommendable.

This highly didactic work has a large number of problems solved and proposed with the numerical solution to many of them, as well as many good figures that illustrate all the topics developed.
