Book Description
Both naturally-occurring and man-made materials are often heterogeneous materials formed of various constituents with different properties and behaviours. Studies are usually carried out on volumes of materials that contain a large number of heterogeneities. Describing these media by using appropriate mathematical models to describe each constituent turns out to be an intractable problem. Instead they are generally investigated by using an equivalent macroscopic description - relative to the microscopic heterogeneity scale - which describes the overall behaviour of the media. Fundamental questions then arise: Is such an equivalent macroscopic description possible? What is the domain of validity of this macroscopic description? The homogenization technique provides complete and rigorous answers to these questions. This book aims to summarize the homogenization technique and its contribution to engineering sciences. Researchers, graduate students and engineers will find here a unified and concise presentation. The book is divided into four parts whose main topics are Introduction to the homogenization technique for periodic or random media, with emphasis on the physics involved in the mathematical process and the applications to real materials. Heat and mass transfers in porous media Newtonian fluid flow in rigid porous media under different regimes Quasi-statics and dynamics of saturated deformable porous media Each part is illustrated by numerical or analytical applications as well as comparison with the self-consistent approach.

Civil Engineering Structures According to the Eurocodes
Author: Xavier Lauzin
Publisher: John Wiley & Sons
ISBN: 1119437032
Category : Technology & Engineering
Languages : en
Pages : 331
Book Description
"This standard assumes that the structure, after completion, is used as intended in the project and subject to planned inspection and maintenance to meet the expected project lifetime and to detect any unforeseen weakness or behavior" (EN 13670 §4.1) An important decision factor in the design of new structures and repairs to existing structures is the lifetime or expected service life. This concept, which is common for civil engineering works, has been extended to all engineering and building works by applying the European Structural Design Codes. This book tries to take stock of the inspection methodologies related to each type of civil engineering work, the various pathologies of concrete structures, and gives examples of the writing of reports.

Project Risks
Author: Geneviève Zembri-Mary
Publisher: John Wiley & Sons
ISBN: 1119671116
Category : Technology & Engineering
Languages : en
Pages : 223
Book Description
Those tasked with the planning and construction of infrastructure and development operations face an increasingly uncertain context in which they must address risks across a number of different fields. These range from the environmental and archaeological to the social, political and financial. As a consequence, the formal and informal practices of stakeholders often incorporate projections of risk and opportunity. Project Risks analyzes this paradigm shift. It reviews the origin and nature of these uncertainties, and the practices implemented by the actors to mitigate or take advantage of them. Paradoxically, these practices generate new risks and power relations that are not compatible with the collaborative planning model. These paradoxes force the rethinking of practices such as project territorialization, risk taking in planning and the responsibility of actors, as well as the societal and political choices that must be made between the realization of projects and the protection of the environment.

3D Printing of Concrete
Author: Arnaud Perrot
Publisher: John Wiley & Sons
ISBN: 1119610788
Category : Technology & Engineering
Languages : en
Pages : 133
Book Description
The introduction of digital manufacturing techniques, such as 3D printing applied to concrete material, opens up new perspectives on the way in which buildings are designed. Research on this theme is thriving and there is a high rate of innovation related to concrete. At the same time, the first life-size constructions made from printed concrete are emerging from the ground. This book presents state-of-the-art knowledge on the different printing processes as well as on the concrete material that must adapt to these new manufacturing techniques, such as new hardware and new printers for concrete. The possibilities in terms of architectural design are discussed as well as the pathways that remain to be uncovered. The book also explores the challenges that researchers and companies expect to overcome as they get closer to democratizing this potential revolution that is the digital manufacturing of concrete.

Control of Cracking in Reinforced Concrete Structures
Author: Francis Barre
Publisher: John Wiley & Sons
ISBN: 1786300524
Category : Technology & Engineering
Languages : en
Pages : 256
Book Description
This book presents new guidelines for the control of cracking in massive reinforced and prestressed concrete structures. Understanding this behavior during construction allows engineers to ensure properties such as durability, reliability, and water- and air-tightness throughout a structure’s lifetime. Based on the findings of the French national CEOS.fr project, the authors extend existing engineering standards and codes to advance the measurement and prediction of cracking patterns. Various behaviors of concrete under load are explored within the chapters of the book. These include cracking of ties, beams and in walls, and the simulation and evaluation of cracking, shrinkage and creep. The authors propose new engineering rules for crack width and space assessment of cracking patterns, and provide recommendations for measurement devices and protocols. Intended as a reference for design and civil engineers working on construction projects, as well as to aid further work in the research community, applied examples are provided at the end of each chapter in the form of expanded measurement methods, calculations and commentary on models.

Dynamic Damage and Fragmentation
Author: David Edward Lambert
Publisher: John Wiley & Sons
ISBN: 1786304082
Category : Technology & Engineering
Languages : en
Pages : 462
Book Description
Engineering structures may be subjected to extreme high-rate loading conditions, like those associated with natural disasters (earthquakes, tsunamis, rock falls, etc.) or those of anthropic origin (impacts, fluid–structure interactions, shock wave transmissions, etc.). Characterization and modeling of the mechanical behavior of materials under these environments is important in predicting the response of structures and improving designs. This book gathers contributions by eminent researchers in academia and government research laboratories on the latest advances in the understanding of the dynamic process of damage, cracking and fragmentation. It allows the reader to develop an understanding of the key features of the dynamic mechanical behavior of brittle (e.g. granular and cementitious), heterogeneous (e.g. energetic) and ductile (e.g. metallic) materials.
