Simulation of drying stresses in Wood. Part I: comparison between one- and two-dimensional models
(1999) In Holz als Roh- und Werkstoff 57(2). p.129-136- Abstract
- A number of rheological models of drying wood have been
presented during the last ten years. At the material point
level, most models show high accuracy. The models in
themselves, however, have no value unless used for improving
wood drying, technique, quality, etc. To achieve
this, they have to be implemented in applicable programs/
methods. In this article, the implementation of a material
model calibrated on small clear wood specimen is presented.
The strain (cup-deformations) and the internal
stresses (indicator of surface checks and internal collapse)
of the boards cross-section are calculated for given moisture
histories. Comparisons... (More) - A number of rheological models of drying wood have been

The strain (cup-deformations) and the internal
stresses (indicator of surface checks and internal collapse)
of the boards cross-section are calculated for given moisture
histories. Comparisons with test results concerning
cupping show that the model can describe the deformation
of a board cross-section. It is also shown that in many
cases a simple analytical solution can be used to determine
the cupping. Comparisons between two-dimensional and
one-dimensional calculations show that the one-dimensional
formulation in many cases is suf®cient to describe
the maximum internal stresses during drying as function
of time. (Less)
