Although wood-water interaction has been studied for decades, the dynamics of water transport during imbibition and its interplay with bound water and deformation are still poorly known, in particular due to a lack of direct internal observations. Moreover, some curious facts have been observed and studied, for example, the permeability depending on the sample length is in contradiction with Darcy’s law which a priori describes liquid transport through a homogenous porous medium. Our original experimental approach, allowing to follow at the same time deformations and bound and free water, makes it possible to clarify some aspects of this problem. %G English %L hal-01711689 %U https://enpc.hal.science/hal-01711689 %~ ENPC %~ CNRS %~ UR-NAVIER %~ PARISTECH %~ IFSTTAR %~ UNIV-EIFFEL %~ IFSTTAR-UNIVEIFFEL
