Fluid invasion into porous materials is very common in natural and industrial processes. The fluid invasion dynamics in simple pore networks are governed by a global balance of capillary, viscous and inertial forces. However, significant local variability in this balance may exist inside natural, heterogeneous porous materials. Here, we imaged slow fluid intrusion in two sister samples of a [...]

Constitutive modelling in geotechnical engineering and applied earth sciences is facing the challenge of assessing the long-term potential of both man-made and natural geohazards. This involves designing engineering operations for length scales and timescales well beyond those observable in the laboratory. In order to bridge the gap between scales, study rock behaviours well beyond their yield [...]
