Stability and Ductility of Steel Structures under Cyclic Loading by Yuhshi Fukumoto,George C. Lee Pdf

The U.S.-Japan Joint Seminar on Stability and Ductility of Steel Structures under Cyclic Loading was held in Osaka, Japan on July 1-3, 1991. This three-day seminar was devoted to five main topics: 1) materials properties and plasticity models, which featured experimental investigations of the material properties of structural steels and plasticity models of the material characteristics under dynamic and cyclic loading conditions; 2) experimental observations, which featured experimental studies of cyclic buckling behavior of steel structural members and frames subjected to dynamic and cyclic loading conditions; 3) analytical modeling, which discussed analytical modeling of the cyclic buckling behavior of steel structural members and frames; 4) design implementation, which emphasized earthquake engineering design of steel structures against cyclic buckling; and 5) future research needs, in which future analytical and experimental research needs on the behavior and design of steel structures subjected to dynamic and cyclic loading conditions were identified. This book contains 30 contributed papers presented at the seminar.

Ductility and Formability of Metals by Giovanni Straffelini Pdf

Ductility and Formability of Metals: A Metallurgical Engineering Perspective uses metallurgical, mechanical and physical principles and concepts to explain ductility while emphasizing the influence of material microstructure on damage mechanisms. Focusing on steel, aluminum, copper, titanium and magnesium alloys, the book examines the strain hardening behaviors of these metals and alloys, the influence of strain rate and temperature, and ductile fracture mechanics. Hot plastic deformation is covered with special consideration given to its interplay with recrystallization phenomena. Other phenomena such as Dynamic Strain Ageing (DSA) and Adiabatic Shear Banding (ASB) are discussed, and metal working applications such as forging, extrusion and machining are included throughout. Methods for control of ductile cracks in metal parts resulting from rolling, forging, extrusion, drawing, and sheet metal forming are also outlined. Provides an overview on the plastic deformation behavior and ductile fracture of steel, aluminum, copper, titanium and magnesium alloys Illustrates the influence of microstructure on yield behavior, strain hardening of metals, and the influence of strain rate and temperature Covers the role of the strain hardening coefficient (n), strain rate index (m), Dynamic Strain Ageing (DSA), and Adiabatic Shear Banding (ASB) Metalworking applications are provided throughout, including forging, rolling, extrusion, wire drawing, sheet metal forming and machining

Stability and Ductility of Steel Structures 2019 by František Wald,Michal Jandera Pdf

For more than forty years the series of International Colloquia on Stability and Ductility of Steel Structures has been supported by the Structural Stability Research Council (SSRC). Its objective is to present the latest results in theoretical, numerical and experimental research in the area of stability and ductility of steel and steel-concrete composite structures. In Stability and Ductility of Steel Structures 2019, the focus is on new concepts and procedures concerning the analysis and design of steel structures and on the background, development and application of rules and recommendations either appearing in recently published Codes or Specifications and in emerging versions, all in anticipation of the new edition of Eurocodes. The series of International Colloquia on Stability and Ductility of Steel Structures started in Paris in 1972, the last five being held in: Timisoara, Romania (1999), Budapest, Hungary (2002), Lisbon, Portugal (2006), Rio de Janeiro, Brazil (2010) and Timisoara, Romania (2016). The 2019 edition of SDSS is organized by the Czech Technical University in Prague.

Stability and Ductility of Steel Structures by T. Usami,Y. Itoh Pdf

The near-field earthquake which struck the Hanshin-Awaji area of Japan before dawn on January 17, 1995, in addition to snatching away the lives of more than 6,000 people, inflicted horrendous damage on the region's infrastructure, including the transportation, communication and lifeline supply network and, of course, on buildings, too. A year earlier, the San Fernando Valley area of California had been hit by another near-field quake, the Northridge Earthquake, which dealt a similarly destructive blow to local infrastructures. Following these two disasters, structural engineers and researchers around the world have been working vigorously to develop methods of design for the kind of structure that is capable of withstanding not only the far-field tectonic earthquakes planned for hitherto, but also the full impact of near-field earthquake.Of the observed types of earthquake damage to steel structures, there are some whose causes are well understood, but many others continue to present us with unresolved problems. To overcome these, it is now urgently necessary for specialists to come together and exchange information.The contents of this volume are selected from the Nagoya Colloquium proceedings will become an important part of the world literature on structural stability and ductility, and will prove a driving force in the development of future stability and ductility related research and design.

Stability and Ductility of Steel Structures (SDSS'99) by D. Dubin&acaron;,M. Iványi Pdf

With the gradual development of rules for designing against instability the idea emerged, in London, in 1974 to hold an International Colloquium treating every aspect of structural instability of steel structures. There have been 17 International Colloquia Stability Sessions around the world, starting with the first one in Paris in 1972, until with the last one in Nagoya in 1997. In Nagoya it was decided to continue the series of travelling colloquia by launching the Sixth Colloquium in September 1999 with the First Session to be held at the "Politehnica" University of Timişoara, România, which will be followed by another in the year 2000 at the Gediminas Technical University in Vilnius, Lithuania, a third one during SSRC's Year 2000 Annual Meeting in the US, and a fourth one in Australia or New Zealand. At present important research projects are in progress around the world, like SAC Joint Venture Project in USA, INCO-COPERNICUS "RECOS" in Europe and others, which are devoted to improve and develop new methods for the safety design of steel structures in seismic zones. Special attention is paid in Europe, USA and Japan to improve the design codes and detailing of seismic resistant steel structures. This was the reason to organise the Session of Nagoya as "Stability and Ductility of Steel Structures" Colloquium. Romania is also a strong seismic territory and therefore, the topic of the Timişoara Session covered both stability and ductility problems. The technical programme of the SDSS'99 Colloquium in Timişoara has been split into nine working sessions.

Ductile Fracture in Metal Forming by Kazutake Komori Pdf

Ductile Fracture in Metal Forming: Modeling and Simulation examines the current understanding of the mechanics and physics of ductile fracture in metal forming processes while also providing an approach to micromechanical ductile fracture prediction that can be applied to all metal forming processes. Starting with an overview of different ductile fracture scenarios, the book then goes on to explain modeling techniques that predict a range of mechanical phenomena that can lead to ductile fracture. The challenges in creating micromechanical models are addressed alongside methods of applying these models to several common metal forming processes. This book is suitable for researchers working in mechanics of materials, metal forming, mechanical metallurgy, and plasticity. Engineers in R&D industries involved in metal forming such as manufacturing, aerospace, and automation will also find the book very useful. Explains innovative micromechanical modeling techniques for a variety of material behaviors Examines how these models can be applied to metal forming processes in practice, including blanking, arrowed cracks in drawing, and surface cracks in upset forging Provides a thorough examination of both macroscopic and microscopic ductile fracture theory

The Effects of Solutes on the Ductile-to-brittle Transition of Refractory Metals by George T. Hahn,A. Gilbert,Robert Isaac Jaffee Pdf

There appear to be two ways in which interstitials promote brittle behavior in Groups V-A and VI-A refractory metals: (1) By locating at the grain boundaries in the form of segregates of precipitates, promoting grain-boundary rupture and crack initiation; and (2) In solid solution by inhibiting dislocation movement and reducing the resistance to crack propagation. Both embrittling effects operate in Group VI-A metals; whereas, only the latter is significant in the Group V-A at the levels of purity currently achieved. The problem of reducing the low-temperature brittleness of Group V-A metals is readily solved through the purity route. Purification of Group V-A metals to interstitial levels well below the solubility limits may be readily accomplished either in the initial purification of the base metal or during melting or consolidation. There are three possible routes to solving the problem of the embrittling effect of interstitials on the Group VI-A metals: (1) the purity route, (2) through working, and (3) through alloying (thermodynamically through strong scavengers, by additions which modify the electron bonding, and via grain-refining dispersions).

The Brittle-Ductile Transition in Rocks by Al G. Duba Pdf

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 56. "The roses seem to have a mildew," Lucy said as I drank my morning coffee. "I'll ask Hugh about it," flashed through my mind, but not past my lips since he's been dead for over two years. I wonder if this isn't typical for his friends and colleagues. Hugh's ability and willingness to help, his unselfish cooperation not just in research but in life, are what made him special to those who worked closely with him. Many who read this volume are familiar with the varied contributions he made to rock mechanics and to high?]pressure research. Consistent with his reputation, the things that impressed me when I first worked with Hugh in 1969 were his enthusiasm for work and his ability to keep pressure systems working well. Although these qualities still come to mind when I think of Hugh, the thing that usually remains is a warm feeling of pleasure at having been his friend and shared part of his life.
