This book presents studies on the plasticity, failure, and damage behavior of materials and structures under monotonic and cyclic loads. Featuring contributions by leading authors from around the globe, it focuses on the description of new effects observed in experiments, such as damage under cyclic loading. It also proposes various simulation models based on different approaches and compares them with tests, taking scaling aspects into account.
This book discusses recent findings and advanced theories presented at two workshops at TU Berlin in 2017 and 2018. It underlines several advantages of generalized continuum models compared to the classical Cauchy continuum, which although widely used in engineering practice, has a number of limitations, such as:
- The structural size is very small.
- The microstructure is complex.
- The effects are localized.
As such, the development of generalized continuum models is helpful and results in a better description of the behavior of structures or materials. At the same time, there are more and more experimental studies supporting the new models because the number of material parameters is higher.
This book commemorates the 80th birthday of Prof. W. Pietraszkiewicz, a prominent specialist in the field of general shell theory. Reflecting Prof. Pietraszkiewicz's focus, the respective papers address a range of current problems in the theory of shells. In addition, they present other structural mechanics problems involving dimension-reduced models. Lastly, several applications are discussed, including material models for such dimension-reduced structures.

This book is the 2nd special volume dedicated to the memory of Gï¿½rard Maugin. Over 30 leading scientists present their contribution to reflect the vast field of scientific activity of Gï¿½rard Maugin. The topics of contributions employing often non-standard methods (generalized model) in this volume show the wide range of subjects that were covered by this exceptional scientific leader.
The topics range from micromechanical basics to engineering applications, focusing on new models and applications of well-known models to new problems. They include micro-macro aspects, computational efforts, possibilities to identify the constitutive equations, and old problems with incorrect or non-satisfying solutions based on the classical continua assumptions.

Innovative technische Projekte mit komplexen Aufgabenstellungen erfordern oft solide Kenntnisse in der Kontinuumsmechanik. Denn hï¿½ufig handelt es sich um Mehrfeldprobleme, die sich im Rahmen klassischer Konzepte der Technischen Mechanik nicht lï¿½sen lassen. Das Buch fï¿½hrt leicht verstï¿½ndlich in das anspruchsvolle Gebiet der Kontinuumsmechanik ein. Der Schwerpunkt liegt bei festen deformierbaren Kï¿½rpern, wobei sich die vorgestellten Konzepte problemlos auch auf Fluide ï¿½bertragen lassen.
Das Lehrbuch gliedert sich in vier Abschnitte: Grundbegriffe und mathematische Grundlagen, Materialunabhï¿½ngige Gleichungen, Materialabhï¿½ngige Gleichungen. Nach einer kurzen Einfï¿½hrung in Aufgaben, Betrachtungsweisen und Modelle der Kontinuumsmechanik werden zunï¿½chst die Grundzï¿½ge der Tensorrechnung vorgestellt. Die folgenden Kapitel behandeln systematisch die materialunabhï¿½ngigen Aussagen der Kontinuumsmechanik, das heiï¿½t die Kinematik, die Kinetik und die Bilanzen. In den abschlieï¿½enden Kapiteln zeigt der Autor anhand der fï¿½r technische Anwendungen besonders wichtigen Teilgebiete (z.B. die lineare Theorie der Elastizitï¿½t und der Thermoelastizitï¿½t) wie die materialunabhï¿½ngigen und die materialabhï¿½ngigen Gleichungen zusammengefasst werden kï¿½nnen. Zahlreiche Beispiele mit vollstï¿½ndigen Lï¿½sungen illustrieren den theoretischen Teil und erleichtern so das Verstï¿½ndnis.
In der 4. Auflage wurden zahlreiche Abschnitte ï¿½berarbeitet und prï¿½zisiert, wobei auch die unterschiedlichen Konzepte der Kontinuumsmechanik noch deutlicher gemacht werden. Zahlreiche Fehler wurden beseitigt. Gleichzeitig wurde die Referenzliteratur erweitert sowie die Liste der weiterfï¿½hrenden Literatur ergï¿½nzt und aktualisiert.
Diese Einfï¿½hrung in die Kontinuumsmechanik richtet sich an Studierende an Universitï¿½ten und Fachhochschulen im Bereich Maschinenbau und Bauingenieurwesen, Physik und Technomathematik sowie an Wissenschaftler und Praktiker in der Industrie. Vorausgesetzt werden Kenntnisse der Hï¿½heren Mathematik, der Physik, der Technischen Mechanik, der Thermodynamik, der Strï¿½mungslehre und der Werkstoffkunde, wie sie zu Beginn der Ausbildung vermittelt werden.
This volume is devoted to an actual topic which is the focus world-wide of various research groups. It contains contributions describing the material behavior on different scales, new existence and uniqueness theorems, the formulation of constitutive equations for advanced materials. The main emphasis of the contributions is directed on the following items - Modelling and simulation of natural and artificial materials with significant microstructure, - Generalized continua as a result of multi-scale models, - Multi-field actions on materials resulting in generalized material models, - Theories including higher gradients, and - Comparison with discrete modelling approaches
This book shows impressively how complex mathematical modeling of materials can be applied to technological problems. Top-class researchers present the theoretical approaches in modern mechanics and apply them to real-world problems in solid mechanics, creep, plasticity, fracture, impact, and friction. They show how they can be applied to technological challenges in various fields like aerospace technology, biological sciences and modern engineering materials.
This book focuses on robust characterization and prediction methods for materials in technical applications as well as the materials' safety features during operation. In particular, it presents methods for reliably predicting material properties, an aspect that is becoming increasingly important as engineering materials are pushed closer and closer to their limits to boost the performance of machines and structures. To increase their engineering value, components are now designed under the consideration of their multiphysical properties and functions, which requires much more intensive investigation and characterization of these materials.
The materials covered in this monograph range from metal-based groups such as lightweight alloys, to advanced high-strength steels and modern titanium alloys. Furthermore, a wide range of polymers and composite materials (e.g. with micro- and nanoparticles or fibres) is covered. The book explores methods for property prediction from classical mechanical characterization-related fields of application, for example, from wear, creep, fatigue and crack growth, to specific surface properties, to dielectric and electrochemical values. As in all fields of modern engineering, the process is often accompanied by numerical simulation and optimization.
This monograph presents approaches to characterize inelastic behavior of materials and structures at high temperature. Starting from experimental observations, it discusses basic features of inelastic phenomena including creep, plasticity, relaxation, low cycle and thermal fatigue.
The authors formulate constitutive equations to describe the inelastic response for the given states of stress and microstructure. They introduce evolution equations to capture hardening, recovery, softening, ageing and damage processes. Principles of continuum mechanics and thermodynamics are presented to provide a framework for the modeling materials behavior with the aim of structural analysis of high-temperature engineering components.
