Neutron imaging and digital volume correlation to analyse the coupled hydro-mechanics of geomaterials
A new approach to characterise the evolution and coupling of deformation and fluid flow in geomaterials is presented. The method exploits some key features of neutrons, namely penetration of dense materials used for triaxial pressure cells, sensitivity to hydrogen and the possibility to distinguish hydrogen from its isotope deuterium (in normal water, H2O, and heavy water, D2O, respectively).
