Summary In this paper, mesoscale hydromechanical simulations are performed to study (1) fracture features and (2) crack-gas permeability coupling evolution in the context of the tensile splitting test. The mesostructure is based on a 2-phase 3-D repr

We consider a model for reactive flows which describes the healing process induced by carbonation of a single crack in concrete structures. The aim of this paper is to study the complex interplay between advection-diffusion mechanisms in a crack-matr

This paper presents the FE formulation for the numerical modelling of chloride ions diffusion accounting for the chloride binding capacity in meso-scale concrete. The finite element formulation is built through a discrete (lattice) finite element mod

In this paper, the authors present a meso-macro numerical approach in order to determine macroscopic diffusivity tensors in heterogeneous quasi-brittle materials such as concrete. The meso-structure is based on a two-phase 3D representation of hetero

This paper presents the formulation of finite element methods for the numerical modeling of a poro-elastic two-phase (aggregates/mixture phase) solid. The displacement and pressure fields are decomposed, following the EAS method, into a regular part
