This unique compendium deals with modeling magnetic media exhibiting hysteresis using computationally efficient phenomenological models that may be utilized in a wide spectrum of both coupled and non-coupled situations. The main factors affecting the behavior of media exhibiting hysteresis — such as magnetic field, mechanical stress and temperature — are dealt with from a higher-level perspective.The volume offers a brief review of well-established definitions of the hysteresis phenomena and widely utilized models. It then presents in its separate chapters a set of innovative efficient multi-component hysteresis models, some of which involves novel operators and/or neural network activation functions as primitive building blocks. Identification methodologies, simulations and experimental verifications for the presented models are also prominently highlighted.This useful reference text offers a great resource material for academics, professionals, researchers and graduate students in electrical and electronic engineering, superconductivity, magnetic materials and mechanical engineering.

This book deals with the mathematical theory of macroeconomic hysteresis, which is the theory of aggregation of microeconomic hysteresis. Microeconomic sunk cost hysteresis is usually represented by relatively simple hysteresis loops with no discrete memory of past economic shocks. It turns out that macroeconomic aggregation leads to the formation of complex multibranch hysteresis with discrete memory of past economic shocks. Consequently, the macroeconomic aggregation of microeconomic hysteresis results in the emergence of new economic phenomena.In the book, the basic properties of macroeconomic hysteresis are mathematically studied. It is demonstrated that certain important properties of macroeconomic hysteresis (such as history-dependent branching, erasure effects of some past economic shocks, geometric features of macroeconomic hysteresis loops, etc.) are insensitive to specific structures of microeconomic hysteresis subject to aggregation. This suggests that the above properties may be viewed as universal. Furthermore, it is pointed out that these aggregation models have the prediction power of future macroeconomic branching, which may be employed for the prediction of future economic evolution.

Co-authored by an international research group with a long-standing cooperation, this book focuses on engineering-oriented electromagnetic and thermal field modeling and application. It presents important contributions, including advanced and efficient finite element analysis used in the solution of electromagnetic and thermal field problems for large and multi-scale engineering applications involving application script development; magnetic measurement of both magnetic materials and components under various, even extreme conditions, based on well-established (standard and non-standard) experimental systems; and multi-level validation based on both industrial test systems and extended TEAM P21 benchmarking platform. Although these are challenging topics, they are useful for readers from both academia and industry.

Today, multi-functional materials such as piezoelectric/ferroelectric ceramics, magneto-strictive and shape memory alloys are gaining increasing applications as sensors, actuators or smart composite materials systems for emerging high tech areas. The stable performance and reliability of these smart components under complex service loads is of paramount practical importance. However, most multi-functional materials suffer from various mechanical and/or electro-magnetical degra-dation mechanisms as fatigue, damage and fracture. Therefore, this exciting topic has become a challenge to intensive international research, provoking the interdisciplinary approach between solid mechanics, materials science and physics. This book summarizes the outcome of the above mentioned IUTAM-symposium, assembling contributions by leading scientists in this area. Particularly, the following topics have been addressed: (1) Development of computational methods for coupled electromechanical field analysis, especially extended, adaptive and multi-level finite elements. (2) Constitutive modeling of non-linear smart material behavior with coupled electric, magnetic, thermal and mechanical fields, primarily based on micro-mechanical models. (3) Investigations of fracture and fatigue in piezoelectric and ferroelectric ceramics by means of process zone modeling, phase field simulation and configurational mechanics. (4) Reliability and durability of sensors and actuators under in service loading by alternating mechanical, electrical and thermal fields. (5) Experimental methods to measure fracture strength and to investigate fatigue crack growth in ferroelectric materials under electromechanical loading. (6) New ferroelectric materials, compounds and composites with enhanced strain capabilities.

With the progress and development of human-robot systems, the coordination among humans, robots, and environments has become increasingly sophisticated. In this Research Topic, we focus on an important field in robotics and automation disciplines, which is commonly defined as behavior-assistant robots. The scope includes but is not limited to: (1) rehabilitation assistive devices, such as rigid/soft exoskeletons, prosthetic systems, orthoses, and intelligent wheelchairs; (2) intelligent medical systems, such as endoscopic robots, surgical robots, and the navigation systems; (3) industrial application devices, such as collaborative manipulators, load-bearing exoskeletons, supernumerary robotic limbs; (4) intelligent domestic devices, such as mobile robots, elderly-care robots, walking-aids robots and so on. The emergence of robot-assisted daily behaviors, based on aforementioned devices, is gradually becoming part of our social lives, which can improve weak motor abilities, enhance physical functionalities, and enable various other benefits.
