This book provides a systematic and standardized approach based on the authors’ over 30 years of research experience with weight function methods, as well as the relevant literature. Fracture mechanics has become an indispensable tool for the design and safe operation of damage-tolerant structures in many important technical areas. The stress intensity factor—the characterizing parameter of the crack tip field—is the foundation of fracture mechanics analysis. The weight function method is a powerful technique for determining stress intensity factors and crack opening displacements for complex load conditions, with remarkable computational efficiency and high accuracy.The book presents the theoretical background of the weight function methods, together with a wealth of analytical weight functions and stress intensity factors for two- and three-dimensional crack geometries; many of these have been incorporated into national, international standards and industrial codes of practice. The accuracy of the results is rigorously verified, and various sample applications are provided. Accordingly, the book offers an ideal reference source for graduate students, researchers, and engineers whose work involves fracture and fatigue of materials and structures, who need not only stress intensity factors themselves but also efficient and reliable tools for obtaining them.

Dieses Buch bietet einen systematischen und standardisierten Ansatz, der auf der über 30-jährigen Forschungserfahrung der Autoren mit Gewichtsfunktionsmethoden sowie auf der einschlägigen Literatur basiert. Die Bruchmechanik ist in vielen wichtigen technischen Bereichen zu einem unverzichtbaren Werkzeug für die Auslegung und den sicheren Betrieb von schadenstoleranten Strukturen geworden. Der Spannungsintensitätsfaktor - der charakterisierende Parameter des Rissspitzenfeldes - ist die Grundlage der bruchmechanischen Analyse. Die Gewichtsfunktionsmethode ist ein leistungsfähiges Verfahren zur Bestimmung von Spannungsintensitätsfaktoren und Rissöffnungsverschiebungen für komplexe Belastungszustände mit bemerkenswerter Berechnungseffizienz und hoher Genauigkeit.Das Buch stellt den theoretischen Hintergrund der Gewichtsfunktionsmethoden sowie eine Fülle von analytischen Gewichtsfunktionen und Spannungsintensitätsfaktoren für zwei- und dreidimensionale Rissgeometrien vor, von denen viele in nationale und internationale Normen und industrielle Regelwerke eingeflossen sind. Die Genauigkeit der Ergebnisse wird genauestens überprüft, und es werden verschiedene Anwendungsbeispiele gegeben. Das Buch ist somit ein ideales Nachschlagewerk für Studenten, Forscher und Ingenieure, die sich mit dem Bruch und der Ermüdung von Werkstoffen und Strukturen befassen und nicht nur die Spannungsintensitätsfaktoren selbst, sondern auch effiziente und zuverlässige Werkzeuge zu deren Ermittlung benötigen.
