Title:
Abstract:	Dieser Beitrag präsentiert computergestützte Modellierungskonzepte zur Vorhersage von Feuchteverläufen und zugehörigen Spannungsfeldern sowie zur numerischen Bestimmung potenzieller Risstiefen von Holzbauteilen. Die vorgestellten Konzepte werden anhand experimenteller Versuchsprogramme validiert und die damit einhergehenden Herausforderungen diskutiert. Ausgewählte Ergebnisse zeigen letztendlich die Möglichkeiten und auch die Relevanz solcher Methoden für den Ingenieurholzbau auf. Computer-based modeling of moisture transport in woodbased materials This article presents computational modeling concepts for predicting moisture gradients, the corresponding stress distributions, and addresses the numerical determination of potential crack depths of wooden components. The concepts presented are validated using experimental test programs, and the associated challenges are discussed. Selected results ultimately show the possibilities as well as the relevance of such methods for timber engineering.
