Book Description
Send me an email at [email protected] to receive the articles cited in this manuscript. This manuscript presents the exciting new technology of additive layer manufacturing (ALM) of metal objects for a broad audience of academic and industry researchers, manufacturing professionals, undergraduate and graduate students, hobbyists, and artists. Innovative applications ranging from rocket nozzles to medical implants illustrate a new world of freedom in design and fabrication, creating objects otherwise not possible by conventional means. New questions naturally arise when using ALM for structural parts. For example, what is the surface quality of the obtained structures? How is it possible to control material defects? How does the microstructure affect the macroscopic mechanical properties? What are the optimal machine parameters for producing components by ALM? At which phase of the design should optimization take place to fully exploit the potential of ALM? Answering these questions is a key point in order to reduce the gap between the requirements set by the technical specifications and the produced part. Therefore, it seems obvious that the industrialization of the ALM process involves the development of mathematical models and algorithms capable of integrating the specificity of the manufacturing process as well as the associated physical phenomena from the first (preliminary) stage. The author presents a bibliographical summary of the various aspects of Additive Manufacturing (AM). Generalities on AM techniques and Ti-6Al-4V obtained by SLM are presented. Then, the mechanical and fatigue behaviours of SLM Ti-6Al-4V structures is analyzed. The sensitivity to different parameters such as HIP post-processing, surface roughness and porosities is discussed.

Book Description
This book presents the concept of functionally graded materials as well as their use and different fabrication processes. The authors describe the use of additive manufacturing technology for the production of very complex parts directly from the three dimension computer aided design of the part by adding material layer after layer. A case study is also presented in the book on the experimental analysis of functionally graded material using laser metal deposition process.

Book Description
This book is devoted to the high-cycle fatigue behaviour of metal components, thus covering essential needs of current industrial design. The new developments included in the book rely on the use of the mesoscopic scale approach in metal fatigue and allow the specific handling of such difficult fatigue problems as multiaxial, non-proportional loading conditions.

Book Description
To determine the carrying capacity of a structure or a structural element susceptible to operate beyond the elastic limit is an important task in many situations of both mechanical and civil engineering. The so-called “direct methods” play an increasing role due to the fact that they allow rapid access to the request information in mathematically constructive manners. They embrace Limit Analysis, the most developed approach now widely used, and Shakedown Analysis, a powerful extension to the variable repeated loads potentially more economical than step-by-step inelastic analysis. This book is the outcome of a workshop held at the University of Sciences and Technology of Lille. The individual contributions stem from the areas of new numerical developments rendering this methods more attractive for industrial design, extension of the general methodology to new horizons, probabilistic approaches and concrete technological applications.

Book Description
The field of additive manufacturing has seen explosive growth in recent years due largely in part to renewed interest from the manufacturing sector. Conceptually, additive manufacturing, or industrial 3D printing, is a way to build parts without using any part-specific tooling or dies from the computer-aided design (CAD) file of the part. Today, mo

Book Description
This volume discusses the basic principles necessary to understand lasers, explains laser interactions with materials, and surveys the wide variety of industrial applications of the major laser types, covering in detail the operating mechanisms of carbon dioxide, Nd:YAG, and excimer lasers. It presents lasers as manufacturing tools rather than laboratory devices.

Book Description
The design of mechanical structures with improved and predictable durability cannot be achieved without a thorough understanding of the mechanisms of fatigue damage and more specifically the relationships between the microstructure of materials and their fatigue properties. Written by leading experts in the field, this book (which is complementary to Fatigue of Materials and Structures: Application to Damage and Design, also edited by Claude Bathias and André Pineau), provides an authoritative, comprehensive and unified treatment of the mechanics and micromechanisms of fatigue in metals, polymers and composites. Each chapter is devoted to one of the major classes of materials or to different types of fatigue damage, thereby providing overall coverage of the field. The book deals with crack initiation, crack growth, low-cycle fatigue, gigacycle fatigue, shorts cracks, fatigue micromechanisms and the local approach to fatigue damage, corrosion fatigue, environmental effects and variable amplitude loadings, and will be an important and much used reference for students, practicing engineers and researchers studying fracture and fatigue in numerous areas of mechanical, structural, civil, design, nuclear, and aerospace engineering as well as materials science.
