An Inelastic Homogenization Framework for Layered Materials with Planes of Weakness
Shabnam J. Semnani, Joshua A. White
Many geologic materials have a composite structure, in which macroscopic mechanical behavior is determined by the properties, shape, and heterogeneous distribution of individual co…
Efficient solvers for hybridized three-field mixed finite element coupled poromechanics
Matteo Frigo, Nicola Castelletto, Massimiliano Ferronato +1
We consider a mixed hybrid finite element formulation for coupled poromechanics. A stabilization strategy based on a macro-element approach is advanced to eliminate the spurious pr…
Algebraically stabilized Lagrange multiplier method for frictional contact mechanics with hydraulically active fractures
Andrea Franceschini, Nicola Castelletto, Joshua A. White +1
Accurate numerical simulation of coupled fracture/fault deformation and fluid flow is crucial to the performance and safety assessment of many subsurface systems. In this work, we…
Multi-Stage Preconditioners for Thermal-Compositional-Reactive Flow in Porous Media
Matthias A. Cremon, Nicola Castelletto, Joshua A. White
We present a family of multi-stage preconditioners for coupled thermal-compositional-reactive reservoir simulation problems. The most common preconditioner used in industrial pract…
A macroelement stabilization for multiphase poromechanics
Julia T. Camargo, Joshua A. White, Ronaldo I. Borja
Strong coupling between geomechanical deformation and multiphase fluid flow appears in a variety of geoscience applications. A common discretization strategy for these problems is…
