Medientyp: E-Artikel Titel: Influence of structural hypotheses on the elastic‐viscoplastic response of shock wave‐loaded plates Beteiligte: Stoffel, Marcus; Vu, Thang Duy; Nguyen, An Danh; Schmidt, Rüdiger; Weichert, Dieter Erschienen: Wiley, 2011 Erschienen in: PAMM, 11 (2011) 1, Seite 291-292 Sprache: Englisch DOI: 10.1002/pamm.201110137 ISSN: 1617-7061 Schlagwörter: General Medicine Entstehung: Anmerkungen: Beschreibung: AbstractIf circular metal plates are subjected repeatedly to impulsive loadings, damage and failure of the structures can occur. In order to predict the damage evolution in finite element simulations, a structural theory combined with viscoplastic constitutive equations acounting for damage is used. However, different structural hypotheses, used in the theoretical model, can lead to variations in the numerical result. Therefore, first‐ and third‐order shear deformations theories are applied in a finite element code. Moreover, local and non‐local damage approaches are used. The aim is to determine the numerical model, which leads to the most accurate results compared to experiments. (© 2011 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim) Zugangsstatus: Freier Zugang
