A shifted interface approach for internal discontinuities in poroelastic media
David Michael Riley, Guglielmo Scovazzi, Ioannis Stefanou
Porous media containing cracks, fractures, or internal discontinuities arise throughout subsurface geomechanics, biomechanics, and materials science. Numerical simulation of the co…

Reinforcement learning-based adaptive time-integration for nonsmooth dynamics
David Michael Riley, Alexandros Stathas, Diego Gutiérrez-Oribio +1
Numerical time integration is fundamental to the simulation of initial and boundary value problems. Traditionally, time integration schemes require adaptive time-stepping to ensure…

Slip, Differentiate, Observe: State and Parameter Estimation for Rate and State Friction from Noisy Data
David Michael Riley, Diego Gutiérrez-Oribio, Ioannis Stefanou
Quantifying frictional properties of interfaces remains a major challenge in both terrestrial and extraterrestrial geomechanics, where available samples, laboratory apparatuses, an…
