Das gut eingefuhrte Werk Ebene Flachentragwerke erscheint nun in der 2. Auflage. Ausgehend von einer Klassifikation der Modelle ebener Flachentragwerke und den Grundgleichungen der linearen Elastizitatstheorie werden zunachst systematisch die Gleichungen fur isotrope Scheiben und Platten abgeleitet. Dabei wird ein didaktisch einheitliches Konzept eingesetzt. Die Gleichungen werden in kartesischen Koordinaten, Polarkoordinaten und schiefwinkligen Koordinaten formuliert. In Erganzung der ersten Auflage wird auch eine Plattentheorie in koordinatenfreier Schreibweise behandelt, so dass der Leser einen leichteren Zugang zu modernen Konzepten der Formulierung von Flachentragwerkstheorien erhalt. Die Diskussion der Plattenmodelle nach Kirchhoff, Mindlin und von Karman zeigt die Moglichkeiten und Grenzen dieser Strukturmodelle.Fur schubstarre und schubelastische Platten mit kleinen Durchbiegungen wird auch anisotropes Materialverhalten einbezogen, und es werden die Strukturgleichungen der klassischen Laminattheorie und der Schubdeformationstheorie erster Ordnung angegeben. Es folgt ein kurzer Einblick in Theorien zur Analyse dreischichtiger Platten. Die Berucksichtigung vorgegebener Temperaturfelder erfolgt fur alle Plattenmodelle im Rahmen der entkoppelten Thermoelastizitat.Der Leser erhalt einen umfassenden Uberblick uber die Anwendung bedeutsamer Strukturmodelle ebener Flachentragwerke. Die nach Aufgabenklassen geordneten zahlreichen Beispiele konnen als Referenzlosungen zur Testung numerischer Verfahren genutzt werden. Die Aufnahme der sogenannten Reduktionsverfahren von Wlassow und Kantorowitsch soll ihre Leistungsfahigkeit fur die Ableitung einfacher und analytischer Naherungslosungen durch die Reduktion der Strukturgleichungen auf eindimensionale Formulierungen verdeutlichen.

This book gives an insight into the current developments in the field of continuum mechanics. Twenty-five researchers present new theoretical concepts, e.g., better inclusion of the microstructure in the models describing material behavior. At the same time, there are also more applications for the theories in engineering practice.In addition to new theoretical approaches in continuum mechanics and applications, the book puts an emphasis on discussing multi-physics problems.

This book gives an update on recent developments in different engineering disciplines such as mechanical, materials, computer and process engineering, focusing on modern engineering design applications. These disciplines provide the foundation for the design and development of improved structures, materials and processes. The modern design cycle is characterized by an interaction of different disciplines and a strong shift to computer-based approaches where only a few experiments are performed for verification purposes. A major driver for this development is the increased demand for cost reduction, which is also connected to environmental demands. In the transportation industry (e.g., automotive), this is connected to the demand for higher fuel efficiency, which is related to the operational costs and the lower harm for the environment. One way to fulfill such requirements is lighter structures and/or improved processes for energy conversion. Another emerging area is the interactionof classical engineering with the health, medical and environmental sector.The chapters are selected contributions of the Advanced Computational Engineering and Experimenting conference, held in July 2022 in Florence, Italy.

This book is published on dedication of Prof. Dr. Igor Sevostianov who passed away in 2021. He was a great Russian-American scientist who made significant contributions in the field of mechanics of heterogeneous media. This book contains research papers from his friends and colleagues in this research field.

This book contains the most recent results in the area of strongly inhomogeneous composite structures, including layered materials as well as continua with microstructure. This collection of papers mainly arises from the Euromech Colloquium No. 626 on ¿Mechanics of High-Contrast Elastic Composites¿. Focus is set on the peculiar mechanical behaviour caused by adjoining widely different structural elements (high contrast) in terms of material and/or geometrical properties.

This book presents current trends in Mechanics of Time Dependent Materials. It covers a number of cutting-edge themes, such as characterization of linear and nonlinear mechanical behavior of viscoelastic materials and their composites, taking into consideration large deformations, low, moderate and large strain rates, as well as failure and fracture phenomena. The contributions are inspired by advanced applications in modern technologies, such as injection molding and extrusion.

Die vollstandig durchgerechneten praxisrelevanten Beispiele in diesem Lehrbuch geben eine anschauliche Einfuhrung in die Festigkeitslehre. Sie wechseln sich mit den theoretischen Grundlagen ab.

B. bei der Behandlung der EULER`schen Stabilitatsfalle, das Kapitel Stabilitatsprobleme wurde insgesamt neu gestaltet und zahlreiche Abbildungen konnten verbessert werden.

The book on advanced structured materials is designed to facilitate teaching and informal discussion in a supportive and friendly environment. The book provides a forum for postgraduate students to present their research results and train their presentation and discussion skills. Furthermore, it allows for extensive discussion of current research being conducted in the wider area of advanced structured materials. Doing so, it builds a wider postgraduate community and offers networking opportunities for early career researchers. In addition to focused lectures, the book provides specialized teaching/overview lectures from experienced senior academics. The 2022 Postgraduate Seminar entitled "e;Advanced Structured Materials: Development - Manufacturing - Characterization - Applications"e; was held from February 28th till March 4th, 2022, in Malta. The book that presented postgraduate lectures had a strong focus on polymer mechanics, composite materials, and additive manufacturing.

Gathering selected contributions to the XIV International Conference on Advanced Mechanical and Power Engineering (CAMPE 2021), held online on October 18-21, 2021, from Kharkiv, Ukraine, this book offers a timely update and extensive information for both researchers and professionals in the field of mechanical and power engineering.

This book presents a collection of articles reporting the current challenges in solid and fracture mechanics. The book is devoted to the 90th birthday of academician Nikita F. Morozov-a well-known specialist in the field of solid and fracture mechanics.

The book introduces advanced theories for deformation, damage, and failure in materials. The overall continuum mechanical framework was marked out and added by creep and damage mechanics of materials at elevated temperatures. The time-dependent and time-independent models of cyclic plasticity for low cycle and thermomechanical fatigue life assessment were specified in a very special manner: instead of three-dimensional statements, only one-dimensional rheological models were discussed. Anisotropic plasticity during non-proportional loading and anisotropy of yield/failure criteria is more and more important in modern applications. It is showing how the limit states of materials can be estimated. In addition, the damage and failure of composite materials demonstrate the possibility to extend continuum mechanics to continuum damage mechanics of composite materials.

This book presents the developments in engineering design application. The chapters on mechanical, materials, computer and process engineering provide the foundation for the design and development of improved structures, materials and processes. They present alternatives with cost reduction and environmental demands. The book content links the interaction of classical engineering with the health, medical and environmental sector.
