Book Description
Este libro presenta una introducción al método de los elementos finitos aplicado al análisis de las estructuras y los sólidos en general, considerando un comportamiento lineal elástico isótropo del material, las deformaciones infinitesimales y el régimen estático de cargas. Inicialmente se describe la formulación del método de los elementos finitos para sólidos, representados en un dominio tridimensional y también mediante sus simplificaciones en los espacios bidimensional y unidimensional. Así mismo, se presenta una aproximación básica para simular el comportamiento mecánico de estructuras laminares a través de la reducción de la geometría a su plano medio.La implementación de cada tipo de formulación se ilustra por medio de los ejemplos de aplicación incluidos al final de algunos capítulos. El libro está dirigido a estudiantes de Ingeniería Civil, Ingeniería Mecánica, Maestría en Estructuras, Maestría en Geotecnia y Maestría en Mecánica que están interesados en conocer el método de los elementos finitos como una técnica para el cálculo del estado de esfuerzos y de deformaciones de sólidos en general.

Book Description
This text is designed for those who already know structural calculation. It starts with the simple exercise of reformulating the direct stiffness method using matrices. The aim is to allow the student to understand the enormous power and generality of the weak formulation for the approximation of strut structure problems by using a formulation which is easy to understand. The correspondence of results of the initial classical formulation with those of the FEM when using linear shape functions and Hermite polynomials allows us to tackle the general formulation of the fundamental concepts of the method more easily. Once the method and the details of its general formulation are understood (although only through its application in a specific structural type), the FEM is presented in a general way, as a procedure for obtaining approximated solutions for partial differential equations. The approaches to field problems and to linear elasticity problems are presented as examples. The method has been now clearly presented and therefore, the selection of the type of element, with the generation of interpolation functions of higher degree and their systematization in element families, can be studied in greater depth. This part finishes with the introduction of the idea of isoparametric transformation that, together with numerical integration, explains the stage of development reached by the method. Finally, the subject relative to plates is dealt with, looking at their specific use as structural elements, and trying to show the difficulty of satisfying the continuity between elements in thin plates, and the shear locking solution in thick plates amongst other things

Book Description
The work of geotechnical engineers contributes to the creation of safe, economic and pleasant spaces to live, work and relax all over the world. Advances are constantly being made, and the expertise of the profession becomes ever more important with the increased pressure on space and resources. This book presents the proceedings of the 15th Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XV PCSMGE), held in Buenos Aires, Argentina, in November 2015. This conference, held every four years, is an important opportunity for international experts, researchers, academics, professionals and geo-engineering companies to meet and exchange ideas and research findings in the areas of soil mechanics, rock mechanics, and their applications in civil, mining and environmental engineering. The articles are divided into nine sections: transportation geotechnics; in-situ testing; geo-engineering for energy and sustainability; numerical modeling in geotechnics; foundations and ground improvement; unsaturated soil behavior; embankments, dams and tailings; excavations and tunnels; and geo-risks, and cover a wide spectrum of issues from fundamentals to applications in geotechnics. This book will undoubtedly represent an essential reference for academics, researchers and practitioners in the field of soil mechanics and geotechnical engineering. In this proceedings, approximately 65% of the contributions are in English, and 35% of the contributions are in Spanish or Portuguese.

Book Description
This book presents an introduction to the Finite Element Method (FEM) and is primarily aimed at students, engineers and scientists who already know structural calculation. It starts from the matrix reformulation of the direct stiffness method to understand the enormous potential of introducing the idea of the weak formulation for the approximation of strut structure problems. The correspondence of results between the initial classical formulation and that of the FEM when using linear shape functions and Hermite polynomials, makes it possible to approach its general formulation more easily as a procedure to obtain approximate solutions of differential equations in partial derivatives. It is essential now to introduce the idea of element, which allows, from the definition of a reduced number of base functions and through a simple combination process, to approximate its real behavior and, through superposition, that of the structure.

Book Description
Containing the proceedings of the 14th Conference on Studies, Repairs and Maintenance of Heritage Architecture (STREMAH 2015), this book provides the necessary scientific knowledge required to formulate regulatory policies and to ensure effective ways of preserving the architectural heritage. First held in 1989, the STREMAH conference attracts an extensive range of quality contributions from scientists, architects, engineers and restoration experts from all over the world dealing with various aspects of heritage buildings. The conference proceedings cover a wide range of topics related to the historical aspects and the reuse of heritage buildings, as well as technical issues on the structural integrity of different types of buildings, such as those constructed with materials as varied as iron and steel, concrete, masonry, wood or earth. Material characterisation techniques are also addressed, including non-destructive tests via computer simulation. Other topics include: Surveying and monitoring; Performance and maintenance; Modern (19th/20th century) heritage; Maritime heritage; Simulation and modelling; Material characterisation; New technologies or materials; Corrosion and material decay; Seismic vulnerability; Assessment and re-use of heritage buildings; Heritage and tourism; Social and economic aspects in heritage; Guidelines, codes and regulations for heritage; Heritage management; Defence heritage; Industrial heritage; Transportation heritage.
