Mesoscale finite element prediction of concrete failure

Modelling of concrete fracture at aggregate level using FEM and DEM based on X-ray μCT images of internal structure

“…The concrete behaviour at the meso-scale may be described with continuum finite element (FE) models [4,5,[11][12][13] and discrete models [2,14,15]. Within discrete methods, the most popular ones are: the classical particle discrete element method (DEM) [16][17][18][19][20][21], interface element models with constitutive laws based on non-linear fracture mechanics [22,23] and lattice methods [2,15,[24][25][26][27][28].…”

A numerical study on chloride migration in cracked concrete using multi-component ionic transport models

“…Šavija et al [16] presented a further simulation with a 3-D geometry based on lattice fracture model [19][20][21][22] to emphasise that cracked concrete is highly inhomogeneous and their transport properties would show significant local variations. Mesoscale finite element models, originally developed for the stress analysis of concrete [23,24], have recently been applied to predict the transport …”

A concrete homogenisation technique at meso-scale level accounting for damaging behaviour of cement paste and aggregates

“…The matter of angular inclusion is treated for instance in [61,1]. Generally, in the mesostructure generation spherical [27,3,62,56,63,64] ellipsoidal or modified ellipsoidal aggregate particles [1,4], or disc shaped particles [65,22] have been used.…”

“…The analyses performed in this paper relate to the meso-scale only, and are aimed to simulate the constitutive behaviour of the material, in order to evaluate the reliability and the limits of the method proposed, as done in [25,3,56,9]. The method will be presented and only the results of uniaxial compression processes will be reported in this work.…”
