Book Description

Este libro presenta una introducción al Método de Elementos Finitos (MEF) y fundamentalmente está dirigido a estudiantes, ingenieros y científicos que conocen el cálculo de estructuras. Se parte de la reformulación matricial del método directo de la rigidez con objeto de que se comprenda el enorme potencial que supone la introducción de la idea de aproximación en la formulación débil del problema de barras. La coincidencia de resultados entre la formulación clásica inicial y la del MEF al utilizar funciones de forma lineales y los polinomios de Hermite, permite abordar más fácilmente su formulación general como procedimiento para obtener soluciones aproximadas de las ecuaciones diferenciales en derivadas parciales.

Book Description

This book covers biodevices, mainly implantable or quirurgical, for the diagnosis or treatment of different pathologies, which benefit from the use of active materials as sensors or actuators. Such active or "intelligent" materials are capable of responding in a controlled way to different external physical or chemical stimuli by changing some of their properties. These materials can be used to design and develop sensors, actuators, and multifunctional systems with a large number of applications for developing biodevices and medical appliances. Current work on these fields entails problems related to synthesis, characterization, modeling, simulation, processing, and prototyping technologies, as well as device testing and validation, all of which are treated in depth in this book, for the several types of active or intelligent materials covered. The research presented in this book helps further development of medical devices, based on the additional functionalities that the use of active or "intelligent" materials, both as sensors and actuators, supplies. The main results exposed may help with the industrial expansion of this kind of materials as part of more complex systems.

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

Factorization Method for Boundary Value Problems by Invariant Embedding presents a new theory for linear elliptic boundary value problems. The authors provide a transformation of the problem in two initial value problems that are uncoupled, enabling you to solve these successively. This method appears similar to the Gauss block factorization of the matrix, obtained in finite dimension after discretization of the problem. This proposed method is comparable to the computation of optimal feedbacks for linear quadratic control problems. - Develops the invariant embedding technique for boundary value problems - Makes a link between control theory, boundary value problems and the Gauss factorization - Presents a new theory for successively solving linear elliptic boundary value problems - Includes a transformation in two initial value problems that are uncoupled

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.
