The European Structural Integrity Society (ESIS) Technical Commitee on Fatigue of Engineering Materials and Structures (TC3) decided to compile a Special Technical Publication (ESIS STP) based on the 115 papers presented at the 6th International Conference on Biaxial/Multiaxial Fatigue and Fracture. The 25 papers included in the STP have been extended and revised by the authors. The conference was held in Lisbon, Portugal, on 25-28 June 2001, and was chaired by Manual De Freitas, Instituto Superior Tecnico, Lisbon. The meeting, organised by the Instituto Superior Tecnico and sponsored by the Portuguese Minesterio da Cienca e da Tecnologia and by the European Structural Integrity Society, was attended by 151 delegates from 20 countries. The papers in the present book deal with the theoretical, numerical and experimental aspects of the Multiaxial fatigue and fracture of engineering materials and structures. They are divided in to the following six sections; Multiaxial Fatigue of Welded Structures; High cycle Multiaxial fatigue; Non proportional and Variable-Amplitude loading; Defects, Notches, Crack Growth; Low Cycle Multiaxial Fatigue; Applications and Testing Methods. As is well-known, most engineering components and structures in the mechanical, aerospace, power generation, and other industries are subjected to multiaxial loading during their service life. One of the most difficult tasks in design against fatigue and fracture is to translate the information gathered from uniaxial fatigue and fracture tests on engineering materials into applications involving complex states of cyclic stress-strain conditions. This book is the result of co-operation between many researchers from different laboratories, universities and industries in a number of countries.

This volume contains 18 papers selected from 90 presented at the Fifth International Conference on Biaxial/Multiaxial Fatigue and Fracture held in Cracow, Poland 8-12 September 1997. The papers in this book deal with theoretical, computational and experimental aspects of the multiaxial fatigue and fracture of engineering materials and structures. The papers are divided into the following four categories: 1. Proportional cyclic loading 2. Non-proportional cyclic loading 3. Variable amplitude and random loading 4. Crack growth Most papers in this publication talk about the behaviour of constructional materials and elements of machines under non-proportional loading and under variable amplitude and random loading, which are more realistic load histories met in industrial practice. Variable amplitude loading under cyclic load with basic frequency and random loading under load with a continuous band of frequency is classified here. This book gives a review of the latest world success and directions of investigations on multiaxial fatigue and fracture. More and more often publications are results of the co-operation of researchers from different laboratories and countries. Seven out of eighteen papers included here were worked out by international authors teams. This is a symptom of the times, when science and investigations know no borders.

Strengere Maßstäbe an die Qualität, Zuverlässigkeit und technische Sicherheit sowie veränderte Konstruktions- und Fertigungsprinzipien in Verbindung mit dem Einsatz neuartiger Hochleistungswerkstoffe stellen zunehmend höhere Anforderungen an die Werkstoffprüfung. Um diesen gerecht zu werden, bedarf es zunehmend der Entwicklung und Umsetzung neuartiger, wissenschaftlich fundierter Verfahren zur Untersuchung von Werkstoffgefüge und -struktur, zur Messung mechanischer und physikalisch-chemischer Eigenschaften sowie für die immer wichtiger werdende zerstörungsfreie Materialprüfung. Im Fokus des Buches stehen moderne, anspruchsvolle Verfahren zur Ermittlung der mechanischen Eigenschaften sowie die analytischen Methoden der Prüfung verformter, metallischer Werkstoffe zur Aufklärung von Struktur-Eigenschafts-Beziehungen. Hierfür werden in den einzelnen Kapiteln jeweils die Grundlagen der Methoden vorgestellt. Danach folgen Darstellungen der modernen Prüf- bzw. Analysetechniken sowie Anwendungsbeispiele aus Forschung und Praxis. Behandelt werden dabei insbesondere neue und modifizierte Prüfverfahren, die aufgrund der Weiterentwicklung von Werkstoffen sowie der Prüf- und Messtechnik, aber auch aufgrund von Anforderungen an die Werkstoffprüfung im Qualitäts-, Sicherheits- und Umweltmanagement erforderlich werden.

Ziel der Arbeit war die Erweiterung des biaxial-planaren Versuchsstandes um die Hochtemperatureignung für die isotherme und anisotherme (thermo-mechanische) niederzyklische Ermüdung. Das Werkstoffverhalten und die Versagensmechanismen der Nickelbasis-Superlegierungen WaspaloyTM und IN738LC wurden anhand von einachsigen Referenzversuchen bestimmt. Die Lebensdauern für die proportionalen biaxial-planaren Dehnungsverhältnisse von 1, 0,6 und -1 zwischen beiden Belastungsachsen unter LCF- und TMF-Beanspruchung lassen sich auf Basis der Gestaltänderungsenergiehypothese mit einachsigen Werten beschreiben. Einzig eine Scherbeanspruchung von IN738LC führt zu einer Lebensdauerverlängerung. Es wird ein Lebensdauermodell auf Basis des Spannungs-Dehnungs-Ansatzes vorgestellt, mit dem die Lebensdauerkorrelation der isothermen und anisothermen sowohl von einachsigen als auch biaxial-planaren Ermüdungsversuchen gelingt.

Micromechanisms of Fracture and Fatigue forms the culmination of 20 years of research in the field of fatigue and fracture. It discusses a range of topics and comments on the state of the art for each. The first part is devoted to models of deformation and fracture of perfect crystals. Using various atomistic methods, the theoretical strength of solids under simple and complex loading is calculated for a wide range of elements and compounds, and compared with experimental data. The connection between the onset of local plasticity in nanoindentation tests and the ideal shear strength is analysed using a multi-scale approach. Moreover, the nature of intrinsic brittleness or ductility of perfect crystal lattices is demonstrated by the coupling of atomistic and mesoscopic approaches, and compared with brittle/ductile behaviour of engineering materials. The second part addresses extrinsic sources of fracture toughness of engineering materials, related to their microstructure and microstructurally-induced crack tortuosity. Micromechanisms of ductile fracture are also described, in relation to the fracture strain of materials. Results of multilevel modelling, including statistical aspects of microstructure, are used to explain remarkable phenomena discovered in experiments. In the third part of the book, basic micromechanisms of fatigue cracks propagation under uniaxial and multiaxial loading are discussed on the basis of the unified mesoscopic model of crack tip shielding and closure, taking both microstructure and statistical effects into account. Applications to failure analysis are also outlined, and an attempt is made to distinguish intrinsic and extrinsic sources of materials resistance to fracture. Micromechanisms of Fracture and Fatigue provides scientists, researchers and postgraduate students with not only a deep insight into basic micromechanisms of fracture behaviour of materials, but also a number of engineering applications.
