One of the intricacies of two-phase flow in porous media is dynamic capillarity, whose effects on fluid flow have already been extensively studied. However, its impact on mechanical behavior is still unclear. One might expect that a change in the hydraulic state would alter the mechanical responses intuitively, but the question is whether the magnitude of these potential alterations is large enough to be worth considering in models and calculations. We addressed this question through numerical simulations. In short, the answer is yes. If you’d like to learn more, our latest publication explores this topic in greater depth.
