Medientyp: E-Artikel Titel: Modelling of material and structural inhomogeneities in timber structures Beteiligte: Jenkel, Christian; Lang, Ronny; Kaliske, Michael Erschienen: Wiley, 2011 Erschienen in: PAMM Sprache: Englisch DOI: 10.1002/pamm.201110107 ISSN: 1617-7061 Schlagwörter: General Medicine Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>The numerical simulation of timber structures by means of FEM has been an object of recent research. Most of the material models developed so far are based on idealized assumptions by disregarding inhomogeneities. Here, models to capture structural inhomogeneities in terms of branches and knots and the resulting deviation in grain course in a three‐dimensional FE analysis are presented. Besides, naturally varying material properties referred to as material inhomogeneities have to be considered in the structural analysis. Due to the insufficient experimental data, the uncertainty model fuzziness is applied. (© 2011 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)</jats:p> Zugangsstatus: Freier Zugang
