This book was released on 2018-09-28 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two dynamic inflation simulation methods are employed for modeling the deployment of folded thin-membrane tubes. The simulations are necessary because ground tests include gravity effects and may poorly represent deployment in space. The two simulation methods are referred to as the Control Volume (CV) method and the Arbitrary Lagrangian Eulerian (ALE) method. They are available in the LS-DYNA nonlinear dynamic finite element code. Both methods are suitable for modeling the interactions between the inflation gas and the thin-membrane tube structures. The CV method only considers the pressure induced by the inflation gas in the simulation, while the ALE method models the actual flow of the inflation gas. Thus, the transient fluid properties at any location within the tube can be predicted by the ALE method. Deployment simulations of three packaged tube models; namely coiled, Z-folded, and telescopically-folded configurations, are performed. Results predicted by both methods for the telescopically-folded configuration are correlated and computational efficiency issues are discussed. Wang, John T. and Johnson, Arthur R.

This book was released on 2001 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reports recently completed structural dynamics experimental activities with new ultra-lightweight and inflatable space structures (a.k.a., "Gossamer" spacecraft) at NASA Langley Research Center, NASA Marshall Space Flight Center, and NASA Goddard Space Flight Center. Nine aspects of this work are covered: 1) inflated, rigidized tubes, 2) active control experiments, 3) photogrammetry, 4) laser vibrometry, 5) modal tests of inflatable structures, 6) in-vacuum modal tests, 7) tensioned membranes, 8) deployment tests, and 9) flight experiment support. Structural dynamics will play a major role in the design and eventually in-space deployment and performance of Grossamer spacecraft. Experimental research and development such as this is required to validate new analysis methods.

This book was released on 2006 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pace of progress in gossamer technology has been strong since the publication of Gossamer Spacecraft: Membrane and Inflatable Structures Technology for Space Applications in 2001. Solar sails are an obvious and public evidence of this trend. But there have been many other advances as well in structures, materials, testing, and systems engineering. Recent Advances in Gossamer Spacecraft focuses on many of these, either as gossamer technology that was not sufficiently represented in the previous volume, or that has had significant growth and activity in the intervening years. The most accurate and up-to-date information has been assembled, reviewed, and presented by an outstanding group of experts.

Available in PDF, EPUB and Kindle. Book excerpt: This publication addresses the most far-reaching and innovative developments in digital practice to have taken place in the last five years. It demonstrates how experimental architects are being challenged at a new rigorous intellectual level and are going beyond the strictures of the conceptual into the realm of the material. As digital techniques are starting to be successfully assimilated and translated into design methodology, they are also, for the first time being seen through to architectural realisation. This is illustrated here at the scale of space, material programme and construction. The title includes the work of high-profile philosophers, architects and engineers, such as Manuel Delanda who wrote 1000 Years of Non-Linear History; Greg Lynn; Foreign Office Architects; and Cecil Balmond of Ove Arup, who has worked with Daniel Libeskind on his proposal for the Spiral Building, London, as well as with Philip Johnson and Studio Baad on the Chavasse Park Project featured here. Cintemorary Techniques in Archtiecture takes architectural publishing's treatment of the digital to a new level, looking at its potential in a realised form as well as a creative medium.

Download or read book Beam Structures written by Erasmo Carrera and published by John Wiley & Sons. This book was released on 2011-07-28 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beam theories are exploited worldwide to analyze civil, mechanical, automotive, and aerospace structures. Many beam approaches have been proposed during the last centuries by eminent scientists such as Euler, Bernoulli, Navier, Timoshenko, Vlasov, etc. Most of these models are problem dependent: they provide reliable results for a given problem, for instance a given section and cannot be applied to a different one. Beam Structures: Classical and Advanced Theories proposes a new original unified approach to beam theory that includes practically all classical and advanced models for beams and which has become established and recognised globally as the most important contribution to the field in the last quarter of a century. The Carrera Unified Formulation (CUF) has hierarchical properties, that is, the error can be reduced by increasing the number of the unknown variables. This formulation is extremely suitable for computer implementations and can deal with most typical engineering challenges. It overcomes the problem of classical formulae that require different formulas for tension, bending, shear and torsion; it can be applied to any beam geometries and loading conditions, reaching a high level of accuracy with low computational cost, and can tackle problems that in most cases are solved by employing plate/shell and 3D formulations. Key features: compares classical and modern approaches to beam theory, including classical well-known results related to Euler-Bernoulli and Timoshenko beam theories pays particular attention to typical applications related to bridge structures, aircraft wings, helicopters and propeller blades provides a number of numerical examples including typical Aerospace and Civil Engineering problems proposes many benchmark assessments to help the reader implement the CUF if they wish to do so accompanied by a companion website hosting dedicated software MUL2 that is used to obtain the numerical solutions in the book, allowing the reader to reproduce the examples given in the book as well as to solve other problems of their own www.mul2.com Researchers of continuum mechanics of solids and structures and structural analysts in industry will find this book extremely insightful. It will also be of great interest to graduate and postgraduate students of mechanical, civil and aerospace engineering.

This book was released on 2022-09-29 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design and Fabrication of Large Polymer Constructions in Space is a ground-breaking study of the polymeric materials, advanced chemical processes, and cutting-edge technology required in the construction of large polymer-based structures for space, when all steps in the process are carried out in the space environment, whether in orbit, in deep space, or on the surface of a moon, asteroid, or planet.The book begins by introducing the fundamentals and requirements of large constructions and inflatable structures for space. The next section of the book focuses on the utilization of polymeric materials within the space environment, examining the effects on materials (vacuum, plasma, temperature), the possible approaches to polymerization both in space and in orbit, the preparation and structure of polymer composites, and the methods for testing materials and structures in terms of strength, defects, and aging. Three chapters then cover how these materials and techniques might be applied to specific categories of construction, including larger space habitats, supporting space structures, and ground infrastructure. Finally, the financial aspects, the consequences for human space exploitation, and the possible future developments are discussed.Using materials science to push the boundaries of construction for space exploration and exploitation, this book is a unique resource for academic researchers and advanced students across polymer science, advanced materials, chemical engineering, construction, and space engineering, as well as for researchers, scientists and engineers at space agencies, companies and laboratories, involved in developing materials or technology for use in space. This is also of great interest to anyone interested in the role of materials science in the building of large space stations, spacecraft, planetary bases, large aperture antenna, radiation and thermal shields, and repairmen sets. Describes the role of polymers in the construction of large space habitats, supporting space structures, and ground infrastructure Explains polymerization in the Earth’s orbit and in space, covering material specifications, control of curing, and the effects of interaction with the external environment Presents the possible testing methods, including strength evaluation, defect detection, and aging tests of materials and constructions
