It has been composed keeping in purview the requirements of those interested in research and development in the field of metal joining. The contents focus on the fundamentals of physics of welded joints, arc welding processes, brazing and soldering, heat flow in welding, welding metallurgy, design of welded joints, and inspection and testing of welded joints and weldability of metals. This book will be useful to both academics and those in the industry.

National leaders often worry that civil wars might spread, but also seem to have little grasp on which civil wars will in fact draw in other states. An ability to understand which civil wars are most likely to draw in outside powers and when this is likely to happen has important policy implications as well as simply answering a scholarly question. Joining the Fray takes existing explanations about which outside states are likely to intervene militarily in civil wars and adds to them explanations about when states join and why. Building on his earlier volume, Is this a Private Fight or Can Anybody Join?, Zachary C. Shirkey looks at how the decision to join a civil war can be intuitively understood as follows: given that remaining neutral was wise when a war began something must change in order for a country to change its beliefs about the benefits of fighting and join the war. This book studies what these changes are, focusing in particular on revealed information and commitment problems.

Joining of Materials and Structures is the first and only complete and highly readable treatment of the options for joining conventional materials and the structures they comprise in conventional and unconventional ways, and for joining emerging materials and structures in novel ways. Joining by mechanical fasteners, integral designed-or formed-in features, adhesives, welding, brazing, soldering, thermal spraying, and hybrid processes are addressed as processes and technologies, as are issues associated with the joining of metals, ceramics (including cement and concrete) glass, plastics, and composites (including wood), as well as, for the first time anywhere, living tissue. While focused on materials issues, issues related to joint design, production processing, quality assurance, process economics, and joint performance in service are not ignored. The book is written for engineers, from an in-training student to a seasoned practitioner by an engineer who chose to teach after years of practice. By reading and referring to this book, the solutions to joining problems will be within one’s grasp. Key Features: · Unprecedented coverage of all joining options (from lashings to lasers) in 10 chapters · Uniquely complete coverage of all materials, including living tissues, in 6 chapters · Richly illustrated with 76 photographs and 233 illustrations or plots · Practice Questions and Problems for use as a text of for reviewing to aid for comprehension * Coverage all of major joining technologies, including welding, soldering, brazing, adhesive and cement bonding, pressure fusion, riveting, bolting, snap-fits, and more * Organized by both joining techniques and materials types, including metals, non-metals, ceramics and glasses, composites, biomaterials, and living tissue * An ideal reference for design engineers, students, package and product designers, manufacturers, machinists, materials scientists

A comprehensive introduction to the concepts of joining technologies for hybrid structures This book introduces the concepts of joining technology for polymer-metal hybrid structures by addressing current and new joining methods. This is achieved by using a balanced approach focusing on the scientific features (structural, physical, chemical, and metallurgical/polymer science phenomena) and engineering properties (mechanical performance, design, applications, etc.) of the currently available and new joining processes. It covers such topics as mechanical fastening, adhesive bonding, advanced joining methods, and statistical analysis in joining technology. Joining of Polymer-Metal Hybrid Structures: Principles and Applications is structured by joining principles, in adhesion-based, mechanical fastened, and direct-assembly methods. The book discusses such recent technologies as friction riveting, friction spot joining and ultrasonic joining. This is used for applications where the original base material characteristics must remain unchanged. Additional sections cover the main principles of statistical analysis in joining technology (illustrated with examples from the field of polymer-metal joining). Joining methods discussed include mechanical fastening (bolting, screwing, riveting, hinges, and fits of polymers and composites), adhesive bonding, and other advanced joining methods (friction staking, laser welding, induction welding, etc.). Provides a combined engineering and scientific approach used to describe principles, properties, and applications of polymer-metal hybrid joints Describes the current developments in design of experiments and statistical analysis in joining technology with emphasis on joining of polymer-metal hybrid structures Covers recent innovations in joining technology of polymer-metal hybrid joints including friction riveting, friction spot joining, friction staking, and ultrasonic joining Principles illustrated by pictures, 3D-schemes, charts, and drawings using examples from the field of polymer-metal joining Joining of Polymer-Metal Hybrid Structures: Principles and Applications will appeal to chemical, polymer, materials, metallurgical, composites, mechanical, process, product, and welding engineers, scientists and students, technicians, and joining process professionals.

The awareness that the churches shaped out of the European Reformations are in an advanced process of unraveling is becoming increasingly sensed by many. This book proposes a way of addressing this unraveling based on the experiences and knowledge of people who have always had to struggle with the unraveling of their own communities and worlds. It takes us outside the circular conversations of the Euro-tribal churches into dialogue with people who have been marginalized to see how they have learned to reenter their formative stories to discover ways of remaking themselves in the unraveling. The book then turns these discoveries into ways the churches can engage their own massive unraveling.

Some countries join interstate wars well after the war has begun, waiting months and often years, and thus changing their beliefs about the wisdom of entering a war. This volume examines why this might be so, focusing on unforeseen events in wars which cause neutral players to update their expectations about the trajectory of the war, therefore explaining why some wars spread while others do not. The author uses a combination of case studies and statistical analysis to test this theory: the Crimean War, the Franco-Prussian War, World War I, and a study of the spread of war since World War II. Designed for courses on and research into war and other international security issues, this book is a must read.

In this new interpretation of antebellum slavery, Anthony Kaye offers a vivid portrait of slaves transforming adjoining plantations into slave neighborhoods. He describes men and women opening paths from their owners' plantations to adjacent farms to go courting and take spouses, to work, to run away, and to otherwise contend with owners and their agents. In the course of cultivating family ties, forging alliances, working, socializing, and storytelling, slaves fashioned their neighborhoods into the locus of slave society. Joining Places is the first book about slavery to use the pension files of former soldiers in the Union army, a vast source of rich testimony by ex-slaves. From these detailed accounts, Kaye tells the stories of men and women in love, "sweethearting," "taking up," "living together," and marrying across plantation lines; striving to get right with God; carving out neighborhoods as a terrain of struggle; and working to overthrow the slaveholders' regime. Kaye's depiction of slaves' sense of place in the Natchez District of Mississippi reveals a slave society that comprised not a single, monolithic community but an archipelago of many neighborhoods. Demonstrating that such neighborhoods prevailed across the South, he reformulates ideas about slave marriage, resistance, independent production, paternalism, autonomy, and the slave community that have defined decades of scholarship.
