The purpose of this paper is to analyse the development and the evolution of the fracture process zone during fracture and damage in quasi-brittle materials. A model taking into account the material details at the mesoscale is used to describe the failure process at the scale of the heterogeneities. This model is used to compute histograms of the relative distances between damaged points. These...

The aim of the current study, IGCCS (2017–2020), is to evaluate feasibility micro-seismic (MS) monitoring CO2 injection into representative storage candidates in North Sea, based on broad and quantitative characterization relevant subsurface behavior with respect geology, geomechanics seismicity. For this purpose, we first group potential sites Sea three different depths. Then, advanced triaxia...

Abstract The recent development of the TOUGH3 code allows for a faster and more reliable fluid flow simulator. At same time, new versions FLAC3D are released periodically, allowing features execution. In this paper, we present first implementation coupling between FLAC3Dv6/7, maintaining parallel computing capabilities coupled geomechanical codes. We compare newly developed version with analyti...

Abstract We propose a phase-field model of shear fractures using the deviatoric stress decomposition. This choice allows us to use general three-dimensional Mohr–Coulomb’s failure function for formulating relations and evaluating peak residual stresses. apply few benchmark problems fracture strain localization report remarkable performance. Our is able capture conjugate modes under biaxial comp...
