Today, I virtually attended the 55th U.S. Rock Mechanics / Geomechanics Symposium, and delivered a presentation in the session of Numerical Modeling in Geomechanics.
The title of this presentation is "Phase-field modeling of mixed-mode fracture in rocks with discontinuities: From laboratory scale to field scale". In this presentation, we validate the capability of recently developed double-phase-field model to model rock cracking problems across different scales. Moreover, due to the length-insensitive feature of double-phase-field model, all modeling parameters involved can be measured from the experimental test even for the simulation in a field-scale problem.
If you are interested at more details, you can refer to the previous post or our paper titled with Phase-field modeling of mixed-mode fracture in rocks with discontinuities: From laboratory scale to field scale. You can also get access to the pre-recorded video of my presentation below, through the YouTube channel of our research group.
