(Complicated problems in nonlinear mechanics pose a challe...)
Complicated problems in nonlinear mechanics pose a challenge - many cannot be solved with existing closed-form methods. You would probably like easier methods for obtaining analytical and numerically exact solutions for finite elements, updated or total Lagrangian formulation, and arc-length methods of nonlinear elastic problem solving. Nonlinear Mechanics, Second Edition gives you what you want - convenient methods of analysis and valuable data for comparison. This is the only book to offer a comprehensive treatment of structural components with variable thickness and a variable modulus of elasticity. It is also the only one to cover closed-form solutions for the dynamic and inelastic analysis of members and plates that are subjected to small and large deformations by including axial and vertical restraints. The author uses exact and approximate solutions for static, dynamic, and inelastic analysis. It also discusses aspects of nonlinear vibration of elastically supported beams, nonlinear response of nonuniform rotor blades, and a new concept of airfoil design. With more than 30% updated and new material, this edition is revised and reorganized to meet the needs of both academia and industry. Easy-to-follow equation derivations, example problems, step-by-step procedures, and iterative approaches create a thorough reference that fills present needs and equips you for the challenges of the future.

(Covering the whole spectrum of vibration theory and its a...)
Covering the whole spectrum of vibration theory and its applications in both civil and mechanical engineering, Mechanical and Structural Vibrations provides the most comprehensive treatment of the subject currently available. Based on the author s many years of experience in both academe and industry, it is designed to function equally well as both a day-to-day working resource for practicing engineers and a superior upper-level undergraduate or graduate-level text. Features a quick-reference format that, Mechanical and Structural Vibrations gives engineers instant access to the specific theory or application they need. Saves valuable time ordinarily spent wading through unrelated or extraneous material. And, while they are thoroughly integrated throughout the text, applications to both civil and mechanical engineering are organized into sections that permit the reader to reference only the material germane to his or her field. Students and teachers will appreciate the book's practical, real-world approach to the subject, its emphasis on simplicity and accuracy of analytical techniques, and its straightforward, step-by-step delineation of all numerical methods used in calculating the dynamics and vibrations problems, as well as the numerous examples with which the author illustrates those methods. They will also appreciate the many chapter-end practice problems (solutions appear in appendices) designed to help them rapidly develop mastery of all concepts and methods covered. Readers will find many versatile new concepts and analytical techniques not covered in other texts, including nonlinear analysis, inelastic response of structural and mechanical components of uniform and variable stiffness, the "dynamic hinge," "dynamically equivalent systems," and other breakthrough tools and techniques developed by the author and his collaborators. Mechanical and Structural Vibrations is both an excellent text for courses in structural dynamics, dynamic systems, and engineering vibration and a valuable tool of the trade for practicing engineers working in a broad range of industries, from electronic packaging to aerospace. Timely, comprehensive, practical--a superior student text and an indispensable working resource for busy engineers Mechanical and Structural Vibrations is the first text to cover the entire spectrum of vibration theory and its applications in both civil and mechanical engineering. Written by an author with over a quarter century of experience as a teacher and practicing engineer, it is designed to function equally well as a working professional resource and an upper-level undergraduate or graduate-level text for courses in structural dynamics, dynamic systems, and engineering vibrations. Mechanical and Structural Vibrations: * Takes a practical, application-oriented approach to the subject * Features a quick-reference format that gives busy professionals instant access to the information needed for the task at hand * Walks readers, step-by-step, through the numerical methods used in calculating the dynamics and vibration problems * Introduces many cutting-edge concepts and analytical tools not covered in other texts * Is packed with real-world examples covering everything from the stresses and strains on buildings during an earthquake to those affecting a space craft during lift-off * Contains chapter-end problems--and solutions--that help students rapidly develop mastery of all important concepts and methods covered * Is extremely well-illustrated and includes more than 300 diagrams, tables, charts, illustrations, and more

(In "Historical Evolutions of Infrastructure: 15,000 Years...)
In "Historical Evolutions of Infrastructure: 15,000 Years of History," Demeter and Anna Fertis explore the history of infrastructure and its evolutions over a course of 15,000 years by concentrating on seven major eras: the Aegean Era, the Era of Wise Men, the Golden Era, the Greco-Roman Era, the Renaissance, the Early Modern European Era, and the Modern Era. The infrastructure is defined in a rather broad sense based on the definition given by the Greek philosopher Socrates, stating that "in order to function at all, a person needs the facilities and arrangements available from community, security, institutions, and economic goods, and that these can only be available when individuals support the concept of community and the responsibilities that it entails. Chief among these responsibilities is the provision of infrastructure and the services it provides." Using this definition of infrastructure, the authors take the readers through the course of a tryly epic voyage across the sea of time to explore the origin and genesis of infrastructure and the many evolutionary changes that followed. They examine the effects on the human race as time progresses, and the indelible marks left by each period's leading minds in the fields of architecture, literature, mathematics, science, engineering, space travel and exploration, technology, and all the arts that influenced the evolution of infrastructure in the various societies that existed over the years. The book is not technical but it addresses technical and non-technical subjects in a simple and enjoyable way so that it can be understood and enjoyed by both casual and serious readers. It provides true history based on the research work of the many male and female researchers in the various fields, and also examines specific topics dealing with urban planning, business and commerse, immigration and migration, anthropological aspects, the fine arts, and other topics that have influenced the evolutiion of our past and present infrastructure. Based on such historical evolutionaly changes the authors theorize about the infrastructure of the future. Today, more than ever before, it is necessary to learn our history and prepare ourselves for the challenges that lie ahead in the twenty-first century. Not having some fair assessment of historical developments may be thought of as having a building without an appropriate foundation to stand it on, or travelling on a ship or an airplane without appropriate navigation. In a not very lengthy way, "Historical Evolutions of Infrastructure" provides the right compass to navigate the reader through the many challenges of the twenty-first century.
