A complete overview of the topic of viscoplastic flow in metallic solids produced by shear banding This book presents novel ideas about inelastic deformation and failure of the material in a clear, concise manner. It exposes readers to information that will allow them to acquire the competence and ability to deal with up-to-date manufacturing and failure processes. It also portrays an interdisciplinary and revolutionary understanding of deformation processes in solids. Shear banding's typical mechanism becomes the active cause of viscoplastic flow and not the passive effect. Viscoplastic Flow in Metallic Solids Produced by Shear Banding begins with discussing the new physical model of multilevel hierarchy and evolution of micro-shear bands. It then covers the physical motivation and heuristic foundations of theoretical description concerning known results in the literature. It examines the difficulties of applying a direct multiscale integration scheme across the scales. It also presents an extension of the representative volume element (RVE) concept using the general theory of propagating the singular surfaces of the microscopic velocity field sweeping the RVE. It also reveals a new formulation of the description of the shear strain rate generated by the multilevel hierarchy of shear bands in the workflow integration approach, in which information from the simulation at different levels flows. This book: Presents fresh ideas about inelastic deformation and failure of materials Provides readers with the competence and ability to deal with up-to-date manufacturing and failure processes Sheds light on the interdisciplinary revolution in the recent understanding of deformation processes in solids Viscoplastic Flow in Metallic Solids Produced by Shear Banding will appeal to researchers studying physical foundations of inelastic deformation of materials and dealing with numerical simulations of manufacturing processes. It is also an excellent resource for graduate and postgraduate students of material science and mechanical engineering faculties.

The electric grid is on the threshold of a paradigm shift. In the past few years, the picture of the grid has changed dramatically due to the introduction of renewable energy sources, advancements in power electronics, digitalization, and other factors. All these megatrends are pointing toward a new electrical system based on Direct Current (DC). DC power systems have inherent advantages of no harmonics, no reactive power, high efficiency, over the conventional AC power systems. Hence, DC power systems have become an emerging and promising alternative in various emerging applications, which include distributed energy sources like wind, solar and Energy Storage System (ESS); distribution networks; smart buildings, remote telecom systems; and transport electrification like electric vehicles (EVs) and shipboard. All these applications are designed at different voltages to meet their specific requirements individually because of the lack of standardization. Thus, the factors influencing the DC voltages and system operation needed to be surveyed and analyzed, which include voltage standards, architecture for existing and emerging applications, topologies and control strategies of power electronic interfaces, fault diagnosis and design of the protection system, optimal economical operation, and system reliability. This groundbreaking new volume presents these topics and trends of DC microgrids, bridging the research gap on DC microgrid architectures, control and protection challenges to enable wide-scale implementation of energy-efficient DC microgrids. Whether for the veteran engineer or the student, this is a must-have for any library.
