This book is devoted to the theory of coupled electro-magneto-thermo-elastic fields excited in different bodies by various sources, both static and dynamic. It presents the classical piezoelectric and piezomagnetic effects, the Mindlin’s electroelastic coupling due to a polarization gradient, and different combinations of these effects with thermoelasticity.

The book is devoted to investigation of a series of problems of convective heat and mass transfer in rotating-disk systems. Such systems are widespread in scienti?c and engineering applications. As examples from the practical area, one can mention gas turbine and computer engineering, disk brakes of automobiles, rotating-disk air cleaners, systems of microclimate, extractors, dispensers of liquids, evaporators, c- cular saws, medical equipment, food process engineering, etc. Among the scienti?c applications, it is necessary to point out rotating-disk electrodes used for experim- tal determination of the diffusion coef?cient in electrolytes. The system consisting of a ?xed disk and a rotating cone that touches the disk by its vertex is widely used for measurement of the viscosity coef?cient of liquids. For time being, large volume of experimental and computational data on par- eters of ?uid ?ow, heat and mass transfer in different types of rotating-disk systems have been accumulated, and different theoretical approaches to their simulation have been developed. This obviously causes a need of systematization and generalization of these data in a book form.

Many historically and artistically important masonry buildings of the world’s architecturalheritageareindireneedofmaintenanceandrestoration.Inorder tooptimizesuchoperationsintermsofcost-e?ectiveness,architecturalimpact andstatice?ectiveness,accuratemodelsofthestructuralbehaviorofmasonry constructions are invaluable. The ultimate aim of such modeling is to obtain important information, such as the stress ?eld, and to estimate the extent of cracking and its evolution when the structure is subjected to variations in both boundary and loading conditions. Although masonry has been used in building for centuries, it is only - centlythatconstitutivemodelsandcalculationtechniqueshavebeenavailable that enable realistic description of the static behavior of structures made of this heterogeneous material whose response to tension is fundamentally d- ferent from that to compression. Important insights on the mechanical behavior of masonry arches and vaults come from as far back as Leonardo [10], Hooke [58], Poleni [92] and many other authors (see [47], [9] and [10] for detailed references). Castigliano, in his famous paper on the Mosca bridge [23], and Signorini, in his studies on masonry beams [97], [98], showed both the possibility and necessity of taking into account the weak tensile strength of masonry material.

Das Lehrbuch führt in die grundlegenden Prinzipien und Arbeitsmethoden der Bruchmechanik und Mikromechanik ein. Im Vordergrund steht die mechanische Beschreibung von Bruchvorgängen, wobei auch materialspezifische Aspekte diskutiert werden. Auf die Behandlung von kontinuumsmechanischen und phänomenologischen Grundlagen folgt ein Einblick in die klassischen Bruch- und Versagenshypothesen sowie in makro- und mikroskopische Phänomene des Bruchs. Ein umfangreicher Teil ist der linearen und elastisch-plastischen Bruchmechanik gewidmet. Weitere Themen sind die Kriechbruchmechanik, Bruchdynamik, Schädigungsmechanik sowie die probabilistische Bruchmechanik. Eine Einführung in die Mikromechanik und die Homogenisierung elastischer, elastisch-plastischer und thermoelastischer Materialien ergänzt das Werk. Die 6. Auflage enthält zahlreiche Erweiterungen, unter anderem auch zu Aspekten der numerischen Behandlung bruchmechanischer Probleme.

Mathematische Optimierung spielt aufgrund der verbreiteten Anwendung des Verfahrens und seiner raschen wissenschaftlichen Entwicklung eine wichtige Rolle im Mathematikstudium. In dem Buch führen die Autoren in die Lineare und Konvexe Optimierung ein und vermitteln darauf aufbauend Fragen der Diskreten und Nichtlinearen Optimierung. Vorausgesetzt werden nur Grundkenntnisse der Linearen Algebra und Analysis. Alle Verfahren werden anhand von ökonomischen Beispielen dargestellt, die einzelnen Schritte im Open-Source-Programm Scilab sind dokumentiert.
