Fault friction under thermal pressurization during large coseismic-slip Part II: Expansion to the model of frictional slip
Alexandros Stathas, Ioannis Stefanou
In Stathas and Stefanou (2022) we presented the frictional response of a bounded fault gouge under largecoseismic slip. We did so by taking into account the evolution of the Princi…
Fault friction under thermal pressurization during large coseismic-slip Part I: Numerical analyses
Alexandros Stathas, Ioannis Stefanou
In this paper, we study the role of thermal pressurization in the frictional response of a fault under large coseismic slip. We investigate the role of the seismic slip velocity, m…
Motion Planning and Robust Tracking for the Heat Equation using Boundary Control
Diego Gutiérrez-Oribio, Yury Orlov, Ioannis Stefanou +1
Robust output tracking is addressed in this paper for a heat equation with Neumann boundary conditions and anti-collocated boundary input and output. The desired reference tracking…
Controlling earthquake-like instabilities using artificial intelligence
Efthymios Papachristos, Ioannis Stefanou
Earthquakes are lethal and costly. This study aims at avoiding these catastrophic events by the application of injection policies retrieved through reinforcement learning. With the…
The role of viscous regularization in dynamical problems, strain localization and mesh dependency
Alexandros Stathas, Ioannis Stefanou
Strain localization is responsible for mesh dependence in numerical analyses concerning a vast variety of fields such as solid mechanics, dynamics, biomechanics and geomechanics. T…
Control instabilities and incite slow-slip in generalized Burridge-Knopoff models
Ioannis Stefanou
Generalized Burridge-Knopoff (GBK) models display rich dynamics, characterized by instabilities and multiple bifurcations. GBK models consist of interconnected masses that can slid…
