Iterative 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 کاملConvergence of iterative coupling for coupled flow and geomechanics
In this paper we study solving iteratively the coupling of flow and mechanics. We demonstrate the stability and convergence of two widely used schemes: the undrained split method and the fixed stress split method. To our knowledge this is the first time that such results have been rigorously obtained and published in the scientific literature. In addition, we propose a new stress split method, ...
متن کاملLaws of crack motion and phase-field models of fracture
Recently proposed phase-field models offer self-consistent descriptions of brittle fracture. Here, we analyze these theories in the quasistatic regime of crack propagation. We show how to derive the laws of crack motion either by using solvability conditions in a perturbative treatment for slight departure from the Griffith threshold, or by generalizing the Eshelby tensor to phase-field models....
متن کاملA Comparison of Techniques for Coupling Porous Flow and Geomechanics
This paper compares three techniques for coupling multiphase porous flow and geomechanics. Sample simulations are presented to highlight the similarities and differences in the techniques. One technique uses an explicit algorithm to couple porous flow and displacements in which flow calculations are performed every timestep and displacements are calculated only during selected timesteps. A seco...
