On preconditioning strategies for geotechnics
Iterative solvers are of increasing interest in geomechanics with the move towards 3D finite element modelling. Potentially, these methods can lead to reduced computational complexity as, unlike direct methods, they do not require the full system matrix to be assembled. In general, however, iterative solvers have not been widely adopted in geomechanics due to problems with convergence. This pap...
متن کاملWere the May 2012 Emilia-Romagna earthquakes induced? A coupled flow-geomechanics modeling assessment
Seismicity induced by fluid injection and withdrawal has emerged as a central element of the scientific discussion around subsurface technologies that tap into water and energy resources. Here we present the application of coupled flow-geomechanics simulation technology to the post mortem analysis of a sequence of damaging earthquakes (Mw= 6.0 and 5.8) in May 2012 near the Cavone oil field, in ...
متن کاملIterative coupling of flow, geomechanics and adaptive phase-field fracture including level-set crack width approaches
In this work, we present numerical studies of fixed-stress iterative coupling for solving flow and geomechanics with propagating fractures in a porous medium. Specifically, fracture propagations are described by employing a phasefield approach. The extension to fixed-stress splitting to propagating phase-field fractures and systematic investigation of its properties are important enhancements t...
متن کاملFrontiers in Computational Physics: Modeling the Earth System
In January 2013, the Journal of Computational Physics announced an open call for quality papers to topical issues on Frontiers in Computational Physics devoted to modelling the Earth System. Computational models play an essential role in diagnosis and prognosis of all elements of the Earth System, from solar variability through space weather, geomechanics, terrestrial climate and weather, down ...
متن کامل[hal-00622157, v1] Micromechanical analysis of stress in an unsatured granular medium
The paper is concerned with a micromechanical formulation of force transmission within an unsaturated soil as a three-phase system composed of idealized spherical particles connected by a pore water menisci network. It is proposed here a tensorial effective stress equation that can be viewed as a generalized Bishop’s equation in which the elusive effective stress parameter χ is elucidated. The ...
