Abstrakt
The layer growing/removing method for determination of residual stresses in orthotropic non-homogeneous discs has been applied as an extension of Kübler's model for analysis of growth stresses in the tree disc. The extended model permits to take account of the orthotropic characteristics and the layered structure of the tree disc. As an illustrative example, growth stresses are calculated in a disc of spruce wood from initial (maturation) stress measured on its free outer surface.
