Abstract
The high temperature process of wood surface
densification increases the wood density in the
transverse direction under compression. The recent
experimental research has pointed out the influence of
the process parameters on the development of the density
profiles in the modified samples. The numerical modelling
can help to optimize the experimental work which is often
expensive due to the large amount of tests required to
check the influence of the process parameters. In the
present work a FEM simulation of the hygro-thermal
behaviour of wood under surface densification is proposed
by using a three-dimensional hygro-thermal model based
on earlier literature approaches. The model is
implemented in a user subroutine of the FEM code Abaqus
starting from the definition of a weak form of
hygro-thermal equations of the problem. The relationship
between the numerical profiles of moisture content and
the experimental density profiles is discussed.
