Book Description
Following Volumes III and IV that dealt with the fracture mechanics of concrete emphasizing both material testing and structural application in general, it was felt that specimen size and loading rate effects for concrete require further attention. The only criterion that has thus far successfully linearized the highly nonlinear crack growth data of concrete is the strain energy density theory. In particular, the crack growth resistance curves plotting the strain energy density factor versus crack growth known as the SR·curves are straight lines as specimen size and loading steps or rates are altered. This allows the extrapolation of data and provides a useful design methodology. This book is unique in that it is devoted specifically to the application of the strain energy density theory to civil engineering structural members made of concrete. Analyzed in detail is the strain softening behavior of concrete for a variety of different components including the influence of steel reinforcement. Permanent damage of the material is accounted for each increment of loading by invoking the mechanism of elastic unloading. This assumption is justified in concrete structures where the effective stiffness depends primarily on the crack growth rate and load history. Crack growth data are presented in terms of SR-curves with emphases placed on scaling specimen size which alone can change the mode of failure from plastic collapse to brittle fracture. Loading rate effects can also be scaled to control failure by yielding and fracture.

Book Description
Understanding and managing damage and cracking in concrete is essential to ensuring the integrity and durability of civil engineering structures. Both theoretical and practical, this book presents a comprehensive approach to these problems by proposing models and numerical modeling strategies that are treated in a manner that is both simplified and efficient. It proposes a wide variety of applications that are derived from research programs and engineering cases. This book also addresses many situations, such as monotonic or cyclic behavior, seismic responses, a description of fast dynamic situations and effects due to the maturation of concrete at an early age in massive structures. Numerous detailed exercises are provided to help students to understand modeling and calculation techniques. Damage and Cracking of Concrete Structures is indeed intended for students, but also for engineers and researchers in the field of mechanics of materials and structures and, more generally, in civil engineering.

Book Description
Explore the wondrous sea and the oddities of human nature in this international bestselling, thrilling epic novel of a Danish port town. Hailed in Europe as an instant classic, We, the Drowned is the story of the port town of Marstal, Denmark, whose inhabitants sailed the world from the mid-nineteenth century to the end of the Second World War. The novel tells of ships wrecked and blown up in wars, of places of terror and violence that continue to lure each generation; there are cannibals here, shrunken heads, prophetic dreams, and miraculous survivals. The result is a brilliant seafaring novel, a gripping saga encompassing industrial growth, the years of expansion and exploration, the crucible of the first half of the twentieth century, and most of all, the sea. Called “one of the most exciting authors in Nordic literature” by Henning Mankell, Carsten Jensen has worked as a literary critic and a journalist, reporting from China, Cambodia, Latin America, the Pacific Islands, and Afghanistan. He lives in Copenhagen and Marstal. “We, the Drowned sets sail beyond the narrow channels of the seafaring genre and approaches Tolstoy in its evocation of war’s confusion, its power to stun victors and vanquished alike…A gorgeous, unsparing novel.”—Washington Post “A generational saga, a swashbuckling sailor’s tale, and the account of a small town coming into modernity—both Melville and Steinbeck might have been pleased to read it.”—New Republic “Dozens of stories coalesce into an odyssey taut with action and drama and suffused with enough heart to satisfy readers who want more than the breakneck thrills of ships battling the elements.”—Publishers Weekly (starred)

Book Description
Restraint and intrinsic stresses in concrete at early ages are vitally important for concrete structures which must remain free of water-permeable cracks, such as water-retaining structures, tunnel linings, locks and dams. The development of hydration heat, stiffness and strength, also the degree of restraint and, especially for high-strength concrete, non-thermal effects, are decisive for sensitivity to cracking. Determining thses stresses in the laboratory and in construction components has led to a clearer understanding of how they develop and how to optimize mix design, temperature and curing conditions. New testing equipment has enabled the effects of all the important parameters to be qualified and more reliable models for predictiong restraint stresses to be developed. Thermal Cracking in Conrete at Early Ages contains 56 contributions by leading international specialists presented at the RILEM Symposium held in October 1994 at the Technical University of Munich. It will be valuable for construction and site engineers, concrete technologists and scientists.

Book Description
Steel Corrosion Induced Concrete Cracking presents the latest advances in the origin, mechanism and development of corrosion-induced cracking in concrete. It investigates topics including expansion coefficient and elastic modulus of steel corrosion, rust layer and rust distribution, spatial distribution of corrosion products, the shape of corrosion-induced cracks and so on. This book concludes by proposing an improved corrosion-induced cracking model, which considers the phenomena of the simultaneous occurrence of corrosion layer accumulation and corrosion filling in concrete. This book will be a valuable reference book for researchers and graduate students in the field of concrete durability and concrete structure, and industry engineers who are concerned with the deterioration mechanisms and the life cycle of reinforced concrete structures. - Proposes a new corrosion-induced concrete cracking model, which takes into account the phenomenon of the simultaneous occurrence of corrosion layer accumulation and corrosion filling paste. - Investigates the parameters and values of expansion coefficients and elastic modulus of steel corrosion, which enables a more rational prediction of concrete surface cracking - Introduces the use of the Gaussian function to describe the non-uniform spatial distribution of corrosion products.

Book Description
The book presents the underlying theories of the different approaches for modeling cracking of concrete and provides a critical survey of the state-of-the-art in computational concrete mechanics. It covers a broad spectrum of topics related to modeling of cracks, including continuum-based and discrete crack models, meso-scale models, advanced discretization strategies to capture evolving cracks based on the concept of finite elements with embedded discontinuities and on the extended finite element method, and extensions to coupled problems such a hygro-mechanical problems as required in computational durability analyses of concrete structures.

Book Description
Many people find the concept of fracture and damage mechanics to be somewhat problematic, mainly because, until recently, close attention in mechanics was focused especially on the strength and resistance of materials. In this sense, to speak of fracture is as uncomfortable for some as it is to speak of a deadly disease. In confronting and preventing a fatal disease, one must understand its complexity, symptoms, and behavior; by the same token, in securing the strength of an engineering structure, one must understand the reasons and type of its potential failure. This book will provide knowledge and insights on this matter to its readers.
