dc.description.abstract
Growing trees respond to mechanical disturbances, e.g. resulting from environmental
forces or gravity, by forming so-called reaction wood, i.e. compression wood in gym-
nosperms and tension wood in angiosperms. It enables the tree to control its posture
by reinforcing and reorienting the axes of stems and branches [1] – a key prerequisite for
reaching large heights. The movement is due to asymmetric cambial activity resulting in
excentric growth and varying growth strains. While the underlying biological mechanisms
of growth strain generation are not yet fully understood, various hypotheses correlating
the induced macroscopic movement with the difference in cell wall structure of reaction
and non-reaction wood have been proposed [2].
On that basis, a homogenization procedure was employed for upscaling of elastic proper-
ties and evaluating the macroscopic effect of growth strains implemented at the cell wall
level. To do so, Herv ́e-Zaoui’s n-layered cylindrical inclusion problem [3] was extended
for anisotropic constituents and utilized for modeling of the cell wall.
Applying geometrically non-linear beam mechanics to a growing branch inclined with
respect to the vector of gravity allows to simulate the reorientation process induced by
growth strains at the cell wall level, introduced via the aforementioned micromechanics
model. In combination with experimental data of the branch shape evolution found in
literature of specific species, growth-related parameters can be deduced, giving access to
new insights into the dynamics of wood growth.
