  Description
Problem solving, classroom exercises The professor will guide the students in applying theoretical concepts and results to problem-solving, fostering critical reasoning at all times. Exercises will be proposed for students to solve, thus acquiring proficiency in using the necessary tools for problem-solving.
Tutorship of group Practical and theoretical problems will be presented for both students and the teacher to solve together. The objective is to guide the student in their learning journey to become an autonomous, competent, and critical learner in their workplace.
Lecture Theoretical classes where the theoretical foundations of the subject will be presented, reasoned, and deduced. At the end of each section, simple exercises clarifying the explained theory will be solved.

Personalized attention
 
Tutorship of group
Description
They will primarily focus on addressing any doubts that may arise throughout the course.

Assessment
  Description Qualification
Mixed tests There will be three types of written assessments:

1. Final exam covering the entire subject.
2. Midterm exam.

An excellent textbook by the Professor of the subject at the School of Civil Engineering, which is not only aimed at his students but has a broader intention and is very interesting for other students or professionals.

The first part of the book constitutes a summary of Elasticity Theory, essential for a rigorous study of Strength of Materials, and it studies the stresses and strains that the applied forces cause inside an elastic body. The second part practically covers all the topics of the program (axial, shear, bending, and torsional stresses, both in statically determinate and indeterminate cases, instability phenomena, and energy theorems).

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

- ORTIZ BERROCAL, L., Resistencia de Materiales, Madrid, McGraw-Hill, (2002 – 2ª edición)

An analysis is carried out of the stress and strain states produced by the solicitations, as well as the relationships between them. Subsequently, the general formulation of the elastic problem is addressed, in its two formulations, to move on to the study of two-dimensional elasticity in Cartesian, cylindrical, and polar coordinates. Finally, the topics of internal potential, plasticity theories, and the theoretical approach of experimental methods (strain gauges and optical) are treated extensively and at an appropriate level.

Basic book for Strength of Materials.

A highly interesting book for the student due to its clear development.

It is a work consisting of two volumes. Both have content adapted to the level of an engineering school. The first volume sets out the fundamentals of Strength of Materials and Structural Calculus, as well as a study of the stresses derived from external loading.

Most chapters include a series of proposed exercises. For each of them, a control value is indicated to check if the exercise resolution has been correct.

This very didactic work has many good figures illustrating all the topics developed.

- GARRIDO, J.A. y FOCES, A., Resistencia de Materiales, Universidad de Valladolid, (1999)

An excellent book for the study of Strength of Materials. The one-dimensional model of bars is extensively developed in a clear and concise manner, and the calculation of stresses in the section is explained, maintaining parallelism and connection between Strength of Materials and Elasticity throughout. Recommended to students for its precision in stress calculation, although some topics covered are beyond the scope of the course, such as the introduction to the Direct Stiffness Method or Torsion in buckling problems. In all topics, there are examples to clarify the preceding theoretical development.

The combined treatment given in the study of tension (compression)-bending follows a development from general to specific, which, although initially more complex, ultimately provides an advantage in terms of clarity of ideas.

A book of mandatory recommendation for anyone wishing to undertake an initial study of Elasticity Theory without getting bored. It explains in a relaxed tone the fundamental concepts and approaches to solving elastic problems. Although the course does not delve deeply into many aspects of Elasticity Theory, this reference is recommended reading for the clarity of ideas it can provide, especially regarding the paths to solving elastic problems.
- ARGÜELLES ÁLVAREZ, R., Cálculo de Estructuras, E.T.S.I. Montes de Madrid, (1981)

This work is structured into two volumes, with the first dedicated to Elasticity, Strength of Materials, and Structural Calculus; and the second to special topics.

In turn, the first volume can be divided into a section dedicated to Elasticity, and a second one on Strength of Materials and Structural Calculus that is perfectly suitable for seminars, specific assignments, or for consulting on special topics within this subject.

As advantages of the book, we can highlight its comprehensive theoretical treatment and the fact that it's written by an author with several texts on these subjects, providing a global perspective. However, as drawbacks, it requires high mathematical knowledge for theoretical exposition, and sometimes its generality can obscure the physical sense.
