Abstract

A three-dimensional finite element program was developed to study the warping of an orthotropic plate. Special features of this program include the capability of modeling moisture-gradient-induced deformation of homogeneous as well as layered sheet materials such as plywood and fiberboard or particleboard. This specially developed finite element analysis is applied here to predict the warping due to an assumed moisture content gradient of a solid wood panel (Douglas fir). How well this analysis simulates the actual behavior of the material can only be determined on the basis of further experimental examination, which, however, was not the subject of this study.

Zusammenfassung

Ein dreidimensionales Finite-Elemente-Programm wurde entwikkelt, um die Verformung rechteckiger Platten zu untersuchen. Spezielle Programmteile simulieren die durch Feuchtegradienten verursachten Deformationen sowohl homogener als auch aus Schichten aufgebauter Platten wie Sperrholz, Faser-oder Spanplatten. Dieses spezielle Analysenprogramm wird hier angewendet, um die Verformung von Vollholzplatten (Douglasien) aufgrund vorgegebener Holzfeuchtegradienten zu berechnen. Wie gut diese Berechnungen das tatsächliche Verhalten von Holzplatten simuliert, kann nur nach weiteren experimentellen Prüfungen beurteil werden, was jedoch nicht im Rahmen dieser Untersuchungen lag.
