Strength of materials is that branch of engineering concerned with the deformation and disruption of solids when forces other than changes in position or equilibrium are acting upon them. The development of our understanding of the strength of materials has enabled engineers to establish the forces which can safely be imposed on structure or components, or to choose materials appropriate to the necessary dimensions of structures and components which have to withstand given loads without suffering effects deleterious to their proper functioning. This excellent historical survey of the strength of materials with many references to the theories of elasticity and structures is based on an extensive series of lectures delivered by the author at Stanford University, Palo Alto, California. Timoshenko explores the early roots of the discipline from the great monuments and pyramids of ancient Egypt through the temples, roads, and fortifications of ancient Greece and Rome. The author fixes the formal beginning of the modern science of the strength of materials with the publications of Galileo's book, "Two Sciences," and traces the rise and development as well as industrial and commercial applications of the fledgling science from the seventeenth century through the twentieth century. Timoshenko fleshes out the bare bones of mathematical theory with lucid demonstrations of important equations and brief biographies of highly influential mathematicians, including: Euler, Lagrange, Navier, Thomas Young, Saint-Venant, Franz Neumann, Maxwell, Kelvin, Rayleigh, Klein, Prandtl, and many others. These theories, equations, and biographies are further enhanced by clear discussions of the development of engineering and engineering education in Italy, France, Germany, England, and elsewhere. 245 figures.
Prelude to war, 1941: Blitzkrieg -- Prelude to war, 1943: war in the Pacific -- 1942-1944: breaking Hitler's grip -- 1944-1945: victory over Germany -- 1943-1945: defeating Japan.
On June 22, 1941, Germany launched the greatest land assault in history on the Soviet Union, an attack that Adolf Hitler deemed crucial to ensure German economic and political survival. As the key theater of the war for the Germans, the eastern front consumed enormous levels of resources and accounted for 75 percent of all German casualties. Despite the significance of this campaign to Germany and to the war as a whole, few English-language publications of the last thirty-five years have addressed these pivotal events. In Ostkrieg: Hitler’s War of Extermination in the East, Stephen G. Fritz bridges the gap in scholarship by incorporating historical research from the last several decades into an accessible, comprehensive, and coherent narrative. His analysis of the Russo-German War from a German perspective covers all aspects of the eastern front, demonstrating the interrelation of military events, economic policy, resource exploitation, and racial policy that first motivated the invasion. This in-depth account challenges accepted notions about World War II and promotes greater understanding of a topic that has been neglected by historians.
Walsh gives a detailed history of Hitler's great failure and a comprehensive account of one of the most important battles of World War II. With full-color strategic maps, 170 b&w photos, and detailed appendices, "Stalingrad" is an exhaustive look at the battle that bled the German army dry.
Provides a modern, practical approach to the understanding and measurement procedures relevant to the fracture of brittle materials This book examines the testing and analysis of the fracture of brittle materials. Expanding on the measurement and analysis methodology contained in the first edition, it covers the relevant measurements (toughness and strength), material types, fracture mechanics, measurement techniques, reliability and lifetime predictions, microstructural considerations, and material/test selection processes appropriate for the analysis of the fracture behavior of brittle materials. The Fracture of Brittle Materials: Testing and Analysis, Second Edition summarizes the concepts behind the selection of a test procedure for fracture toughness and strength, and goes into detail on how the statistics of fracture can be used to assure reliability. It explains the importance of the role of microstructure in these determinations and emphasizes the use of fractographic analysis as an important tool in understanding why a part failed. The new edition includes a significant quantity of material related to the fracture of biomaterials, and features two new chapters—one on thermal shock, the other on the modeling of the fracture process. It also expands on a discussion of how to treat the statistics of fracture strength data to ensure reliability. Provides practical analysis of fracture toughness and strength Introduces the engineering and materials student to the basic concepts necessary for analyzing brittle fracture Contains new statistical analysis procedures to allow for the prediction of the safe design of brittle components Contains real-world examples to assist the reader in applying the concepts to their own research, material development, and quality-control needs The Fracture of Brittle Materials: Testing and Analysis, Second Edition is an important resource for all students, technicians, engineers, scientists, and researchers involved in the study, analysis, creation, or testing of ceramics.
Russia is a post-communist country struggling to adapt to the modern world economically and politically. In the twenty-first century, Russia faces postmodern social, cultural, and political problems with its old policy of deterrence. For Russia's political leaders and military planners, three scenarios define their postmodern setting: 1) the world's leading military and economic powers, with the exception of China, are market-based economies and political democracies; 2) the revolution in military affairs, based on advances in information, electronics, and communications, is driving both civil and military technology innovation; and 3) the Cold War's fundamental war-fighting premises, such as deterrence based on nuclear weapons and on conventional armed forces organized and trained for massive wars of attrition, have changed radically. These points' implications for future Russian strategy are profound, Stephen J. Cimbala and Peter Rainow argue. Russia faces an increased presence of its former adversary, the United States, in adjacent territories; an increasingly assertive NATO, which includes many of Moscow's former allies; and continued fighting in Chechnya. Ominously, China aspires to overtake Russia as the world's second-ranked military power and establish its hegemony over the Pacific basin. In short, Russia confronts a radically new political and military world order that demands adapting to postmodern thinking about deterrence and defense. The danger is that Russia, realizing that it lags behind in leveraging modern technology for military purposes and that it must scrap its dependence on conscription, now relies on nuclear weapons as its first line of deterrence against either nuclear or conventional attack.
It is a real pleasure to write the Foreword for this book, both because I have known and respected its author for many years and because I expect this book’s publication will mark an important milestone in the continuing worldwide development of microsystems. By bringing together all aspects of microsystem design, it can be expected to facilitate the training of not only a new generation of engineers, but perhaps a whole new type of engineer – one capable of addressing the complex range of problems involved in reducing entire systems to the micro- and nano-domains. This book breaks down disciplinary barriers to set the stage for systems we do not even dream of today. Microsystems have a long history, dating back to the earliest days of mic- electronics. While integrated circuits developed in the early 1960s, a number of laboratories worked to use the same technology base to form integrated sensors. The idea was to reduce cost and perhaps put the sensors and circuits together on the same chip. By the late-60s, integrated MOS-photodiode arrays had been developed for visible imaging, and silicon etching was being used to create thin diaphragms that could convert pressure into an electrical signal. By 1970, selective anisotropic etching was being used for diaphragm formation, retaining a thick silicon rim to absorb package-induced stresses. Impurity- and electrochemically-based etch-stops soon emerged, and "bulk micromachining" came into its own.
Stephen Hall argues that democracies can preserve their norms and values from increasing attacks and backsliding by better understanding how authoritarian regimes learn. He focuses on the post-Soviet region, investigating two established authoritarian regimes, Belarus and Russia, and two hybrid-regimes, Moldova and Ukraine, with the aim of explaining the concept of authoritarian learning and revealing the practices that are developed and the sources of that learning. Hall finds clear signs of collaboration between countries in developing best survival practices between authoritarian-minded elites, and demonstrates that learning does not just occur between states, rather it can happen at the intra-state level, with elites learning lessons from previous regimes in their own countries. He highlights the horizontal nature of this learning, with authoritarian-minded elites developing methods from a range of sources to ascertain the best practices for survival. Post-Soviet regional organisations are crucial for the development and sharing of these survival practices as they provide 'learning rooms' and training exercises.
“Monumental.” —The New York Times Book Review Pulitzer Prize-finalist Stephen Kotkin has written the definitive biography of Joseph Stalin, from collectivization and the Great Terror to the conflict with Hitler's Germany that is the signal event of modern world history In 1929, Joseph Stalin, having already achieved dictatorial power over the vast Soviet Empire, formally ordered the systematic conversion of the world’s largest peasant economy into “socialist modernity,” otherwise known as collectivization, regardless of the cost. What it cost, and what Stalin ruthlessly enacted, transformed the country and its ruler in profound and enduring ways. Building and running a dictatorship, with life and death power over hundreds of millions, made Stalin into the uncanny figure he became. Stephen Kotkin’s Stalin: Waiting for Hitler, 1929–1941 is the story of how a political system forged an unparalleled personality and vice versa. The wholesale collectivization of some 120 million peasants necessitated levels of coercion that were extreme even for Russia, and the resulting mass starvation elicited criticism inside the party even from those Communists committed to the eradication of capitalism. But Stalin did not flinch. By 1934, when the Soviet Union had stabilized and socialism had been implanted in the countryside, praise for his stunning anti-capitalist success came from all quarters. Stalin, however, never forgave and never forgot, with shocking consequences as he strove to consolidate the state with a brand new elite of young strivers like himself. Stalin’s obsessions drove him to execute nearly a million people, including the military leadership, diplomatic and intelligence officials, and innumerable leading lights in culture. While Stalin revived a great power, building a formidable industrialized military, the Soviet Union was effectively alone and surrounded by perceived enemies. The quest for security would bring Soviet Communism to a shocking and improbable pact with Nazi Germany. But that bargain would not unfold as envisioned. The lives of Stalin and Hitler, and the fates of their respective dictatorships, drew ever closer to collision, as the world hung in the balance. Stalin: Waiting for Hitler, 1929–1941 is a history of the world during the build-up to its most fateful hour, from the vantage point of Stalin’s seat of power. It is a landmark achievement in the annals of historical scholarship, and in the art of biography.

The American Heritage History of World War II was first published in 1966. At the time, author and Pulitzer Prize-winning journalist C.L. Sulzberger received widespread praise for his authoritative account of the six-year war that involved more than fifty-six nations, resulted in the death of some 22 million people, and shaped the course of history. His work became a standard reference on the war.Stephen E. Ambrose, one of the most highly regarded historians of our time, oversaw a major revision of this classic work. Seamlessly incorporating new material and insights, Ambrose produced a comprehensive and riveting account of the war's key characters and events.
Stalingrad is a comprehensive history of the greatest battle of World War II, a defining moment in the struggle on the Eastern Front, which has been called the Verdun of World War II.
This book maps changing definitions of statehood in Russia, Ukraine and Belarus as a result of their exclusion from an expanding Europe. The authors examine the perceptions of the place of each state in the international political system and its foreign policy choices, and draw comparisons across the region.
Written by world-renowned authorities on mechanics, this classic ranges from theoretical explanations of 2- and 3-D stress and strain to practical applications such as torsion, bending, and thermal stress. 1961 edition.
Bringing together the work of nine leading historians, and superbly illustrated with contemporary photography and colour maps, The Second World War gives readers a comprehensive understanding of all aspects of history's greatest conflict. The period from 1939 to 1945 saw some of the most devastating and remarkable events in living memory. Labouring beneath a daily burden of fear, sacrifice, deprivation and uncertainty, soldiers and civilians of all nationalities were driven to extremes of selfless loyalty, dogged determination or bitter cruelty by the demands of a world at war. This book tells the stories of the men and women who lived and died during the Second World War, from politicians to factory workers, and from High Command to the conscripted men on the front lines. The experience of war is brought to life through a wealth of contemporary documentation, private writings and historical research, whilst the political, military and historical significance of the war is assessed and examined. From Europe's Western and Eastern Fronts to the war at sea, and from the Pacific to the Mediterranean and North Africa, every fighting front of the Second World War is covered in this truly comprehensive volume.
