Medientyp: E-Artikel Titel: Assessment of asymmetric crack initiation in open‐hole plates using a coupled stress and energy criterion Beteiligte: Rosendahl, Philipp L.; Weißgraeber, Philipp; Stein, Nicolas; Becker, Wilfried Erschienen: Wiley, 2016 Erschienen in: PAMM Sprache: Englisch DOI: 10.1002/pamm.201610071 ISSN: 1617-7061 Schlagwörter: General Medicine Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>An application of the finite fracture mechanics concept to open‐hole plates subject to combined tensile and bending loading is presented. In finite fracture mechanics, the simultaneous satisfaction of both, a stress and an energy criterion, is enforced as a condition for crack initiation. Efficient modeling and closed‐form expressions for the dependence of the stress and energy quantities on governing structural and material parameters allow for a comprehensive numerical analysis of the onset of asymmetric crack patterns. The obtained failure load predictions are found to agree well with a cohesive zone model and experimental data from literature. (© 2016 Wiley‐VCH Verlag GmbH & Co.
