The aim of this book is to summarize the current most effective methods for modeling, simulating, and optimizing metal forming processes, and to present the main features of new, innovative methods currently being developed which will no doubt be the industrial tools of tomorrow. It discusses damage (or defect) prediction in virtual metal forming, using advanced multiphysical and multiscale fully coupled constitutive equations. Theoretical formulation, numerical aspects as well as application to various sheet and bulk metal forming are presented in detail. Virtual metal forming is nowadays inescapable when looking to optimize numerically various metal forming processes in order to design advanced mechanical components. To do this, highly predictive constitutive equations accounting for the full coupling between various physical phenomena at various scales under large deformation including the ductile damage occurrence are required. In addition, fully 3D adaptive numerical methods related to time and space discretization are required in order to solve accurately the associated initial and boundary value problems. This book focuses on these two main and complementary aspects with application to a wide range of metal forming and machining processes.

The importance of cultural contacts in the East Mediterranean has long been recognized and is the focus of ongoing international research. Fieldwork in the Aegean, Egypt, Cyprus, and the Levant continues to add to our understanding of the nature of this contact and its social and economic significance, particularly to the cultures of the Aegean. Despite sophisticated discussion of the archaeological evidence, in particular on the part of Aegean and Mediterranean archaeologists, there has been little systematic attempt to incorporate anthropological perspectives on materiality and exchange into archaeological narratives of this material. This book addresses that gap and integrates anthropological discourse on contact, examining exchange systems, the gift, notions of geographical distance and power, colonization, and hybridization. Furthermore, it develops a social narrative of culture contact in the Mediterranean context, illustrating the reasons communities chose to engage in international exchange, and how this impacted the construction of identities throughout the region. While traditional archaeologies in the East Mediterranean have tended to be reductive in their approach to material culture and how it was produced, used, and exchanged, this book reviews current research on material culture, focusing on issues such as the biography of objects, inalienable possessions, and hybridization - exploring how these issues can further illuminate the material world of the communities of the Bronze Age Mediterranean.

The continuous evolution of high-power and high-frequency electronic devices demands advanced semiconductor technologies. The proposed GaN p-FET device architecture incorporates a p-GaN source region that enables the simultaneous formation of two-dimensional electron gas (2DEG) and two-dimensional hole gas (2DHG) channels. This dual-channel mechanism enhances carrier confinement and mobility, offering a pivotal pathway toward high-performance GaN-based electronics. This simulation study systematically examines key parameters to optimize device configurations: Mg 2+ doping (0.05 to 50 × 10 19 cm − 3 ), contact metal work function (4.0 to 6.3 eV), AlGaN layer thickness (4 to 25 nm), and Al mole fraction (0.1 to 0.45) in relation to the performance of p-GaN source layer n-GaN/AlGaN/GaN double heterostructure FETs. Extensive analyses reveal that a GaN pFET with a 5 nm p-GaN layer doped with 1 × 10 19 cm − 3 Mg 2+ and a 10 nm AlGaN layer with an Al mole fraction of 0.2, demonstrates superior performance metrics. Compared to state-of-the-art technologies, this specific device configuration achieves optimal threshold voltage (~ |4| V) control, high I ON /I OFF ratios (0.39 × 10 12 ), and minimized leakage current, essential for reliable high-performance operations. Additionally, the study highlights the critical impact of the contact metal work function, with a work function of 5.15 eV significantly reducing contact resistivity and minimizing leakage current, enhancing device efficiency. These findings highlight that precise control over doping, material thickness, and composition is essential for optimizing GaN pFET performance and reliability for next-generation electronic applications.

Following the long tradition of the Schuler Company, the Metal For- ming Handbook presents the scientific fundamentals of metal forming technology in a way which is both compact and easily understood. Thus, this book makes the theory and practice of this field accessible to teaching and practical implementation. The first Schuler \"Metal Forming Handbook\" was published in 1930. The last edition of 1966, already revised four times, was translated into a number of languages, and met with resounding approval around the globe. Over the last 30 years, the field of forming technology has been rad- ically changed by a number of innovations. New forming techniques and extended product design possibilities have been developed and introduced. This Metal Forming Handbook has been fundamentally revised to take account of these technological changes. It is both a text- book and a reference work whose initial chapters are concerned to pro- vide a survey of the fundamental processes of forming technology and press design. The book then goes on to provide an in-depth study of the major fields of sheet metal forming, cutting, hydroforming and solid forming. A large number of relevant calculations offers state of the art solutions in the field of metal forming technology. In presenting tech- nical explanations, particular emphasis was placed on easily under- standable graphic visualization. All illustrations and diagrams were compiled using a standardized system of functionally oriented color codes with a view to aiding the reader's understanding.
