A non-invasive method for measuring the three-dimensional displacement field and liquid
content distribution in a wetting and swelling material using X-ray tomographic imaging is introduced.
The method is demonstrated here in monitoring the evolution of 3D deformation and water content
distributions in cylindrical samples of swelling clay material wetted in a constant total volume. The measurements
were carried out using a high-resolution microtomographic device (SkyScan 1172) and image
voxel size 24 µm. The results obtained are repeatable and appear qualitatively correct and plausible.
They are useful e.g. in validating models involving transport of water and the resulting deformation of
swelling materials. The method is potentially applicable also in other materials and processes involving
liquid transport and deformation.

Time-resolved X-ray microtomographic measurement of water transport in wood-fibre reinforced composite material
Miettinen, Arttu; Harjupatana, Tero; Kataja, Markku; Fortino, Stefania; Immonen, Kirsi (Institute of Physics Publishing Ltd., 2016)Natural fibre composites are prone to absorb moisture from the environment which may lead to dimensional changes, mold growth, degradation of mechanical properties or other adverse effects. In this work we develop a ... -
