This textbook provides a concise introduction to the mathematical theory of fluid motion with the underlying physics. Different branches of fluid mechanics are developed from general to specific topics. At the end of each chapter carefully designed problems are assigned as homework, for which selected fully worked-out solutions are provided. This book can be used for self-study, as well as in conjunction with a course in fluid mechanics.
Die nichtlineare Festkörpermechanik beschäftigt sich mit der Lösung nichtlinearer Zustandsgleichungen von physikalischen Körpern wie Gummi, Metallen, Keramiken, Holz, lebenden Geweben usw. Ein Kontinuumansatz ermöglicht die Erklärung physikalischer Phänomene ohne Kenntnis der inneren Mikrostruktur. Die einmalige Kombination von Themengebieten richtet sich an fortgeschrittene Studenten der Mechanik und der numerischen Methoden gleichermaßen. (05/00)
Starting with background principles in fluid mechanics and thermodynamics, this title discusses axial flow turbines and compressors, centrifugal pumps, fans, and compressors, and radial flow gas turbines, hydraulic turbines, and wind turbines.
This book combines the perspectives of materials science of Superplasticity, on the one hand, and those of design and mechanics, on the other, in order to provide a holistic view of materials, design, mechanics and performance which will lead to useful solutions of societal benefits, in addition to providing great intellectual challenges. After considering the experimental evidence for superplasticity in different classes of materials, the book discusses the physics-based models, along with their advantages and limitations. Then, the analyses for superplastic forming available in the framework of continuum mechanics, finite element analysis and numerical simulations are presented. Finally, the authors highlight some successful industrial applications. This book is recommended as a text book for courses on Superplasticity and as supplementary use for courses on Materials Processing, Manufacturing, High Temperature Deformation, Nanotechnology and Mechanical Behavior of Materials. Persons working in Department of Materials Science and Engineering, Physics, Mechanics, Mechanical Engineering, Aerospace Engineering, Metallurgy, Ceramics and Geo-sciences are likely to find the book to be useful. It is also recommended as a reference source for practicing engineers involved in the design, processing and manufacture of industrial components, which exploit the unique properties associated with superplastic materials.
This is the first book which exploits concepts and tools of global nonlinear dynamics for bridging the gap between theoretical and practical stability of systems/structures, and for possibly enhancing the engineering design in macro-, micro- and nano-mechanics. Addressed topics include complementing theoretical and practical stability to achieve load carrying capacity; dynamical integrity for analyzing global dynamics, for interpreting/predicting experimental behavior, for getting hints towards engineering design; techniques for control of chaos; response of uncontrolled and controlled system/models in applied mechanics and structural dynamics by also considerung the effect of system imperfections; from relatively simple systems to multidimensional models representative of real world applications; potential and expected impact of global dynamics for engineering design.
The protection of pedestrians is the most important global road safety priority. This is the first book to provide a detailed treatment of the physical processes which occur when pedestrians and cyclists are struck by motorised vehicles. The principal focus is to show how pedestrian and cyclist pre-impact movements and vehicle design influence subsequent injury outcome. This involves recourse to several academic disciplines: epidemiology, mechanics, and anatomy/physiology. Therefore this book presents pedestrian and cyclist impact from a biomechanical perspective. It features a detailed treatment of the physics of pedestrian and cyclist impact, as well as a review of the accident databases and the relevant injury criteria used in the assessment of pedestrian and cyclist injuries. New data detailing the kinematics of the impact processes are presented, and the relationship between vehicle impact speed and projection distance and the relative importance of ground related injuries compared to vehicle related injuries is assessed in detail. The final focus is on the complex relationship between vehicle design and pedestrian and cyclist injury outcome in the event of a collision. This book is a one stop source for understanding the mechanics of pedestrian and cyclist impact and is therefore of significant value to both new and established researchers.
This book offers a comprehensive and updated discussion of fatigue, stress corrosion and corrosion-fatigue, using many high quality figures. Stress corrosion and corrosion-fatigue are treated both from the electrochemical and fracture mechanics standpoints. This textbook, suitable for students, researchers and engineers, gathers the experience of more than 20 years of teaching fracture mechanics, fatigue and corrosion to professional engineers and running experimental tests and verifications to solve practical problems in engineering applications. As such, it is a comprehensive blend of fundamental knowledge and technical tools to address the issues of fatigue and corrosion. The book initiates with a systematic description of fatigue from a phenomenological point of view, since the early signs of submicroscopic damage in few surface grains and continues describing, step by step, how these precursors develop to become mechanically small cracks and, eventually, macrocracks whose growth is governed by fracture mechanics. But fracture mechanics is also introduced to analyze stress corrosion and corrosion assisted fatigue in a rather advanced fashion. The author dedicates a particular attention to corrosion starting with an electrochemical treatment that mechanical engineers with a rather limited knowledge of electrochemistry will well digest without any pain. The electrochemical introduction is considered an essential requirement to the full understanding of corrosion that is essentially an electrochemical process. All stress corrosion aspects are treated, from the generalized film rupture-anodic dissolution process that is the base of any corrosion mechanism to the aggression occurring in either mechanically or thermally sensitized alloys up to the universe of hydrogen embrittlement, which is described in all its possible modes of appearance. Multiaxial fatigue and out-of-phase loading conditions are treated in a rather comprehensive manner together with damage progression and accumulation that are not linear processes. Load spectra are analyzed also in the frequency domain using the Fourier transform in a rather elegant fashion full of applications that are generally not considered at all in fatigue textbooks, yet they deserve a special place and attention. The issue of fatigue cannot be treated without a probabilistic approach unless the designer accepts the shame of one-out-of-two pieces failure. The reader is fully introduced to the most promising and advanced analytical tools that do not require a normal or lognormal distribution of the experimental data, which is the most common case in fatigue. But the probabilistic approach is also used to introduce the fundamental issue of process volume that is the base of any engineering application of fatigue, from the probability of failure to the notch effect, from the metallurgical variability and size effect to the load type effect. Fractography plays a fundamental role in the post mortem analysis of fatigue and corrosion failures since it can unveil the mystery encrypted in any failure.
