INTRODUCCIÓN AL MÉTODO DE LOS ELEMENTOS FINITOS


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.




Engineering Computation of Structures: The Finite Element Method


Book Description

This book presents theories and the main useful techniques of the Finite Element Method (FEM), with an introduction to FEM and many case studies of its use in engineering practice. It supports engineers and students to solve primarily linear problems in mechanical engineering, with a main focus on static and dynamic structural problems. Readers of this text are encouraged to discover the proper relationship between theory and practice, within the finite element method: Practice without theory is blind, but theory without practice is sterile. Beginning with elasticity basic concepts and the classical theories of stressed materials, the work goes on to apply the relationship between forces, displacements, stresses and strains on the process of modeling, simulating and designing engineered technical systems. Chapters discuss the finite element equations for static, eigenvalue analysis, as well as transient analyses. Students and practitioners using commercial FEM software will find this book very helpful. It uses straightforward examples to demonstrate a complete and detailed finite element procedure, emphasizing the differences between exact and numerical procedures.




Análisis estructural mediante el método de los elementos finitos. Introducción al comportamiento lineal elástico


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.

Human Systems Engineering and Design


Book Description

This book focuses on novel design and systems engineering approaches, including theories and best practices, for promoting a better integration of people and engineering systems. It covers a range of hot topics related to: development of activity-centered and user-centered systems; interface design and human-computer interaction; usability and user experience; cooperative, participatory and contextual models; emergent properties of human behavior; innovative materials in manufacturing, and many more. Particular emphasis is placed on applications in sports, healthcare, and medicine. The book, which gathers selected papers presented at the 1st International Conference on Human Systems Engineering and Design: Future Trends and Applications (IHSED 2018), held on October 25-27, 2018, at CHU-Université de Reims Champagne-Ardenne, France, provides researchers, practitioners and program managers with a snapshot of the state-of-the-art and current challenges in the field of human systems engineering and design.




Mechanics of Sandwich Structures


Book Description

The main advantages of sandwiches as structural components are now well known and well-established. Due to the progress in polymer science and engineering and advances in manufacturing processes, sandwich structures can blend various functional and structural properties and therefore lead to highly innovating systems. The current difficulty to overcome is to provide designers with proper methodologies and tools that could enable them to design improved sandwich structures. Such dedicated design tools should be efficient, reliable, flexible and user-friendly. They should be based on advanced knowledge of sandwich behaviour at global and local scales. Such approach relies on our capability to test, identify, control and model structure performances. The impressive variety of core and face materials and the rapid developments in forming processes give new opportunities to design components which have more complex shapes and higher integrated functional and structural properties. Interest in sandwiches is permanently growing in industry and refined testing and modelling approaches should be encouraged to set up relevant guidelines to design reliable advanced structures. The European Society for Mechanics sponsored the EUROMECH 360 Colloquium on the 'Mechanics of Sandwich Structures' in Saint-Etienne, France, on 13 - 15 May 1997. The main purpose of EUROMECH 360 was to go into the most recent progresses in sandwich analysis and design, including mechanical modelling and testing. It was expected that the Colloquium should contribute to define new research directions to support development of advanced applications in strategic industrial sectors such as ground transportations or building and civil engineering.




Structural & Construction Conference


Book Description

Objective of conference is to define knowledge and technologies needed to design and develop project processes and to produce high-quality, competitive, environment- and consumer-friendly structures and constructed facilities. This goal is clearly related to the development and (re)-use of quality materials, to excellence in construction management and to reliable measurement and testing methods.




Earthquake Resistant Buildings


Book Description

This concise work provides a general introduction to the design of buildings which must be resistant to the effect of earthquakes. A major part of this design involves the building structure which has a primary role in preventing serious damage or structural collapse. Much of the material presented in this book examines building structures. Due to the recent discovery of vertical components, it examines not only the resistance to lateral forces but also analyses the disastrous influence of vertical components. The work is written for Practicing Civil, Structural, and Mechanical Engineers, Seismologists and Geoscientists. It serves as a knowledge source for graduate students and their instructors.
