Composite structures are most efficient in performance and production cost when combined with smart materials making them adaptable to changing operational conditions. The specific production processes of composites offer the possibility to integrate more functions thus making the structure more valuable. Active functions can be realized by smart materials, e.g. morphing, active vibration control, active structure acoustic control or structure health monitoring. The foundation is a sound understanding of materials, design methods, design principles, production technologies and adaptronics. Along the complete process chain this disciplines together deliver advanced lightweight solutions for applications ranging from mechanical engineering to vehicles, airframe and finally space structures. This book provides the scientific foundations as well as inspiring new ideas for engineers working in the field of composite lightweight structures.

Fatigue of the pressurized fuselages of transport aircraft is a significant problem all builders and users of aircraft have to cope with for reasons associated with assuring a sufficient lifetime and safety, and formulating adequate inspection procedures. These aspects are all addressed in various formal protocols for creating and maintaining airworthiness, including damage tolerance considerations. In most transport aircraft, fatigue occurs in lap joints, sometimes leading to circumstances that threaten safety in critical ways. The problem of fatigue of lap joints has been considerably enlarged by the goal of extending aircraft lifetimes. Fatigue of riveted lap joints between aluminium alloy sheets, typical of the pressurized aircraft fuselage, is the major topic of the present book. The richly illustrated and well-structured chapters treat subjects such as: structural design solutions and loading conditions for fuselage skin joints; relevance of laboratory test results for simple lap joint specimens to riveted joints in a real structure; effect of various production and design related variables on the riveted joint fatigue behaviour; analytical and experimental results on load transmission in mechanically fastened lap joints; theoretical and experimental analysis of secondary bending and its implications for riveted joint fatigue performance; nucleation and shape development of fatigue cracks in riveted longitudinal lap joints; overview of experimental investigations into the multi-site damage for full scale fuselage panels and riveted lap joint specimens; fatigue crack growth and fatigue life prediction methodology for riveted lap joints; residual strength predictions for riveted lap joints in a fuselage structure. The major issues of each chapter are recapitulated in the last section.

Esta publicación incluye de forma integra los textos de los Reales Decretos que configuran el contexto global de la ICT, junto con sus Órdenes de desarrollo. Los cuatro documentos forman parte del cuerpo de lo que ha sido el Reglamento del ICT desde su nacimiento, si bien en la actualidad el Reglamento de ICT es una disposición diferente del Reglamento de Instalación y Mantenimiento de Equipos y Sistemas de Telecomunicación. Su órden de aparición en el texto es el mismo que el expuesto a continuación, por entender que es el más conveniente en lo referido a la compresión y posiblemente relevancia.

El tratado de Procedimientos generales de Construcción tiene por objeto el estudio de las reglas técnicas y métodos de trabajo que condicionan la ejecución de las obras públicas. Este Tratado está también estrechamente relacionado con los cursos de Derecho administrativo y exige, de una parte, el estudio y la redacción de los proyectos, y de obra la preparación de presupuestos y liquidaciones, algunas de las cuales toman a veces un carácter contencioso.

Human error plays a significant role in many accidents involving safety-critical systems, and it is now a standard requirement in both the US and Europe for Human Factors (HF) to be taken into account in system design and safety assessment. This book will be an essential guide for anyone who uses HF in their everyday work, providing them with consistent and ready-to-use procedures and methods that can be applied to real-life problems. The first part of the book looks at the theoretical framework, methods and techniques that the engineer or safety analyst needs to use when working on a HF-related project. The second part presents four case studies that show the reader how the above framework and guidelines work in practice. The case studies are based on real-life projects carried out by the author for a major European railway system, and in collaboration with international companies such as the International Civil Aviation Organisation, Volvo, Daimler-Chrysler and FIAT.

Salir del ensimismamiento, experimentar las potencialidades de la formación y la cultura, abrir caminos por el mundo, tales podrían ser los enunciados de una de las más fructíferas líneas del movimiento regenerador surgido de la gran crisis española de final del siglo XIX. Algunos de sus resultados son ya bien conocidos, entre los cuales destaca con luz propia el de las pensiones en el extranjero, muy en particular de las gestionadas por la JAE desde 1907. El presente libro aborda esa misma tematica en el campo de la formacion y el desarrollo de la ciencia aplicada. Desde esa misma fecha, en efecto, iniciativas semejantes cristalizaron en pensiones de ampliacion de estudios para ingenieros y de formacion en nuevas tecnicas y procedimientos empiricos para obreros manuales procedentes de fabricas, talleres y granjas nacionales. Su organizacion fue confiada poco despues a un organismo estatal autonomo, la Junta de Patronato de Pensiones de Ingenieros y Obreros en el Extranjero (JPIOE), que desarrollara su obra ininterrumpidamente, bajo diferentes nombres, hasta mas aca de la guerra civil. Pero sobre este esqueleto basico, el trabajo se adentra ademas en un amplio espectro de cuestiones que le son inseparables. Como telon de fondo esta todo el desarrollo de la enseñanza profesional, la eclosion de las politicas sociales desarrolladas desde 1920 por el nuevo Ministerio de Trabajo, la aparicion de un nuevo tipo de reflexiones sobre la gestion del Estado y sobre la manera de abordar los problemas de la productividad del trabajo y su organizacion ante las nuevas exigencias de competitividad de la segunda revolucion industrial, las vicisitudes de la innovacion tecnica y de su transferencia y adaptacion a nuevos contextos y, en fin, los interrogantes mas generales acerca de las relaciones entre educacion y desarrollo economico.

A comprehensive approach to the air vehicle design process using the principles of systems engineering Due to the high cost and the risks associated with development, complex aircraft systems have become a prime candidate for the adoption of systems engineering methodologies. This book presents the entire process of aircraft design based on a systems engineering approach from conceptual design phase, through to preliminary design phase and to detail design phase. Presenting in one volume the methodologies behind aircraft design, this book covers the components and the issues affected by design procedures. The basic topics that are essential to the process, such as aerodynamics, flight stability and control, aero-structure, and aircraft performance are reviewed in various chapters where required.

El presente estudio pretende entender la obra y a su autor desde la propia materialidad de la arquitectura, de los planos y su geometría, así como del análisis de lo que Acero dejó escrito al defenderse de los furibundos ataques recibidos por las dificultades de la cimentacion de las torres, tras los que se adivinan los rechazos que su arquitectura heterodoxa produjo. La Catedral es hoy un testimonio de la evolucion de las ideas, plasmado en piedra. Al contrario de lo que se entiende a veces, los monumentos no son obras acabadas, cerradas, estaticas e imperecederas. La continua transformacion en que consiste la Arquitectura hace que a lo largo del tiempo se acumulen y evolucionen las ideas y los monumentos las expresen en su materialidad. La Catedral de Cadiz es paradigma de ello, del cambio de las ideas que se produce en el ultimo barroco.
