Mechanics of Strain Gradient Materials (CISM International Centre for Mechanical Sciences #600)
by Samuel Forest Albrecht BertramOver the past 50 years, strain gradient material theories have been developed for the continuum modeling of size effects in materials and structures in terms of their elasticity, plasticity and fracturing. This book puts forward a unifying perspective to combine existing theories involving the higher order gradient of the strain tensor, or of plastic strain. It begins by reviewing experimental findings on the existence (or non-existence) of size effects on the mechanics of materials. In turn, the book devises first, second and higher order strain gradient theories from general principles, and presents constitutive frameworks that satisfy thermodynamic requirements. The special case of strain gradient plasticity is then developed and illustrated via computational analyses of size effects on the plasticity of metals at small scales. In closing, the book explains the origin of gradient effects in the case of lattice structures by drawing on homogenization theory.

Mechanics of Wood Machining
by Endre Magoss Etele CsanádyWood is one of the most valuable materials for mankind, and since our earliest days wood materials have been widely used. Today we have modern woodworking machine and tools; however, the raw wood materials available are continuously declining. Therefore we are forced to use this precious material more economically, reducing waste wherever possible. This new textbook on the "Mechanics of Wood Machining" combines the quantitative, mathematical analysis of the mechanisms of wood processing with practical recommendations and solutions. Bringing together materials from many sources, the book contains new theoretical and experimental approaches and offers a clear and systematic overview of the theory of wood cutting, thermal loading in wood-cutting tools, dynamic behaviour of tool and work piece, optimum choice of operational parameters and energy consumption, the wear process of the tools, and the general regularities of wood surface roughness. Diagrams are provided for the quick estimation of various process parameters. This book will be useful for scientists, graduate and postgraduate students, and practising engineers seeking a deeper understanding of physical phenomena associated with real woodworking processes.
Mechanics of Wood Machining
by Endre Magoss Etele CsanádyThe new edition of this textbook, while largely retaining the proven chapter structure of the previous editions, combines the quantitative, mathematical analysis of the mechanisms of wood processing with practical recommendations and solutions. It presents new theoretical and experimental approaches and offers a clear and systematic overview of the theory of wood cutting, thermal loading in wood-cutting tools, optimum choice of operational parameters, dynamic behavior of tool and workpiece, stability problems in wood machining, energy requirements, the wear process of tools and a unique analysis of surface roughness. In general, diagrams are provided to help quickly estimate various process parameters. As a modern and powerful tool, the process optimization procedure is also included, and amply demonstrated in worked-out examples. In this edition, new and updated material has been added in many sections: roughly a third of the book has been rewritten and a quarter of the figures are new. In addition, many figures have been revised for clarity. The authors are confident that this revised and expanded edition will continue to meet the needs of all those working in the field of wood machining.

Mechanik – Mikromechanik – Nanomechanik: Vom Eigenschaftsverstehen zur Eigenschaftsverbesserung
by Goerg H. MichlerUm das mechanische Verhalten von Werkstoffen einerseits besser zu verstehen und andererseits gezielt verbessern zu können, müssen die Prozesse und Mechanismen, die bei mechanischer Belastung im Material in Abhängigkeit von den Materialstrukturen ablaufen (die sog. „Struktur- Eigenschafts-Korrelationen“), bekannt sein. Grundlegend sind die Prozesse auf mikro- und nanoskopischer Größenebene, d.h. im Größenbereich von 0,1 mm bis herab zu 0,1 nm (d.h. sog. Mikro- und Nanomechanik). Der Autor charakterisiert anschaulich diese mikro- und nanomechanischen Mechanismen mit aussagefähigen Schemata und Bildern auf der Grundlage hauptsächlich von elektronenmikroskopischen Analysen. Neben allgemeingültigen Prozessen und Mechanismen wird auch auf materialspezifische Effekte (z.B. Crazes, Chevrons, Dünnschichtfließen) eingegangen.Die Produktfamilie WissensExpress bietet Ihnen Lehr- und Lernbücher in kompakter Form. Die Bücher liefern schnell und verständlich fundiertes Wissen.
Mechanik – smart gelöst
by Peter KerstenDieses Buch bietet Studierenden in MINT-Fächern eine optimale Hilfestellung beim Erlernen der Grundlagen der Physik. Typische Aufgaben der Mechanik werden dabei Schritt für Schritt erklärt und mit Hilfe leistungsstarker Software aus den Bereichen Tabellenkalkulation, Computeralgebra und technisch-wissenschaftlichem Rechnen gelöst.

Mechanism-Based Assessment of Structural and Functional Behavior of Sustainable Cottonid (Werkstofftechnische Berichte │ Reports of Materials Science and Engineering)
by Ronja Victoria ScholzRonja Victoria Scholz assesses the performance of cellulose-based Cottonid for implementation as sustainable construction material. Quasi-static and fatigue tests are performed in varying hygrothermal test conditions using mechanical testing systems in combination with integrable climate chambers. To investigate humidity-driven actuation properties, customized specimen holders are designed. Accompanying microstructural in situ experiments in analytical devices enable a profound understanding of effective material-specific damage and failure mechanisms. The findings are transferred into strength-deformation diagrams as well as Woehler curves, which enable a comparative evaluation of several process-related and environmental influencing factors and can directly be used for dimensioning of Cottonid elements for structural applications. The interpretation of thermoelastic material reponse during loading is used as scientific value for lifetime prediction. Comprehensive investigations on industrial standard materials as well as structurally optimized Cottonid variants provide a scientific basis for categorizing material’s structural and functional performance towards common technical plastics and wood.
