Atmospheric Re-Entry Vehicle Mechanics

Atmospheric Re-Entry Vehicle Mechanics by Patrick Gallais
English | PDF | 2007 | 65 Pages | ISBN : 3540736468 | 20.2 MB

Ballistic reentry vehicles, capsules and planetary probes are the fastest human designed objects to fly through planet’s atmospheres. With velocities over Mach 20, RV’s have to dissipate a huge kinetic energy, and environment may exceed 100 g’s at center of mass, 100 bars stagnation pressure and 100 MW/m² on nosetip. Design of thermal protection system is a formidable material engineering problem. Vehicle conception covers large discipline realms, among which Aerodynamics and Flight Mechanics are essential as they only can provide necessary aeroshell shape, mass and inertia properties and tolerances to achieve adequate environment and trajectory performance. Capsules and probes have different missions and entry conditions but approaches and methods are identical. Based on a long engineering experience, this book offers a comprehensive and state of the art analysis of aerodynamic and flight mechanic entry topics. In addition, it provides a large set of application exercises and solutions. It is addressed to university and engineering school students, as well as engineers in aerospace companies and government agencies, or simply curious readers.

Mechanical Vibration: Where Do We Stand?

Mechanical Vibration: Where Do We Stand?

Mechanical Vibration: Where Do We Stand? by Isaac Elishakoff
English | PDF(True) | 2007 | 487 Pages | ISBN : 3211685863 | 21.6 MB

''There is always a delightful sense of movement, vibration and life"". Theodore Robinson (1852-1896) "/ have never solved a major mechanical or interpretive problem at the keyboard. I have always solved it in my mind". Jorge Bolet (1914-1990) The idea of this book stems from the realization that scientists, not unlike laymen, should occasionally interrupt their regular work and reflect on the past, to see both the accomplishments and the drawbacks, so as to be able to plan for future research in the "proper" perspective. But an inquisitive reader may ask: Can one really document in any field, let alone mechanical vibrations (whose very name signifies change), ''where do we stand"? Did not a Greek philosopher famously claim that one cannot enter a river twice? Another, on an even more sophisticated note, added that actually it is impossible to enter a river even once!

Uncertain Logics, Variables and Systems by Zdzislaw Bubnicki
English | PDF | 2002 | 140 Pages | ISBN : 3540432353 | 3.8 MB

The ideas of uncertain variables based on uncertain logics have been introduced and developed for a wide class of uncertain systems. The purpose of this mo- graph is to present basic concepts, definitions and results concerning the uncertain variables and their applications to analysis and decision problems in uncertain systems described by traditional mathematical models and by knowledge rep- sentations. I hope that the book can be useful for graduate students, researchers and all readers working in the field of control and information science. Especially for those interested in the problems of uncertain decision support systems and unc- tain control systems. I wish to express my gratitude to my co-workers from the Institute of Control and Systems Engineering of Wroclaw University of Technology, who assisted in the preparation of the manuscript. My special thanks go to Dr L.Siwek for the valuable remarks and for his work concerning the formatting of the text.

Seismic Vulnerability Assessment and Retrofitting Strategies for Masonry Infilled Frame Building by Andre Filipe Furtado
English | PDF EPUB (True) | 2023 | 365 Pages | ISBN : 3031203712 | 204 MB

This book reports on a comprehensive experimental characterization of the material, mechanical and dynamic properties of masonry infill walls. It analyses the critical parameters affecting their out-of-plane seismic behavior, including the effects of the panel support conditions, gravity load, and previous damage. Further, it offers an extensive review of infill masonry strengthening strategies and reports on the experimental assessment of various textile-reinforced mortar (TRM) strengthening solutions. It also presents the development, implementation and calibration of a numerical model to simulate the infill panels’ seismic behavior, with the corresponding findings of various tests to assess the seismic vulnerability of an infilled RC structure. All in all, this outstanding PhD thesis offers a comprehensive review of masonry infill walls, and a timely overview of numerical and experimental methods for testing and preventing the out-of-plane seismic collapse of RC buildings.

Multiscale Multibody Dynamics: Motion Formalism Implementation

Multiscale Multibody Dynamics: Motion Formalism Implementation by Jielong Wang
English | PDF,EPUB | 2023 | 366 Pages | ISBN : 9811984409 | 47.7 MB

This book presents a novel theory of multibody dynamics with distinct features, including unified continuum theory, multiscale modeling technology of multibody system, and motion formalism implementation. All these features together with the introductions of fundamental concepts of vector, dual vector, tensor, dual tensor, recursive descriptions of joints, and the higher-order implicit solvers formulate the scope of the book’s content. In this book, a multibody system is defined as a set consisted of flexible and rigid bodies which are connected by any kinds of joints or constraints to achieve the desired motion. Generally, the motion of multibody system includes the translation and rotation; it is more efficient to describe the motion by using the dual vector or dual tensor directly instead of defining two types of variables, the translation and rotation separately. Furthermore, this book addresses the detail of motion formalism and its finite element implementation of the solid, shell-like, and beam-like structures. It also introduces the fundamental concepts of mechanics, such as the definition of vector, dual vector, tensor, and dual tensor, briefly. Without following the Einstein summation convention, the first- and second-order tensor operations in this book are depicted by linear algebraic operation symbols of row array, column array, and two-dimensional matrix, making these operations easier to understand. In addition, for the integral of governing equations of motion, a set of ordinary differential equations for the finite element-based discrete system, the book discussed the implementation of implicit solvers in detail and introduced the well-developed RADAU IIA algorithms based on post-error estimation to make the contents of the book complete.
