This study investigates the influences of pore-structure and mortar properties on the fracture
behaviour of geopolymer foamed concrete. The discrete element method (DEM) is utilised to …

The existing bridge stock, both in the EU and globally, contains several bridges that are
reaching the end of their design-life, many of them showing signs of deterioration. Although …

The FE 2 method systematically translates macro kinematic constraints to the underlying
(micro) RVEs and extracts the effective RVE responses to macro continuum in an …

Cracking simulation in concrete-like structures is the subject of numerous investigations of
computational kind, in which different modeling techniques based on either smeared or …

A finite element model simulates concrete cracking using a smeared crack approach. The
uncertainty of the crack width model is verified by the experimental data from tests of …

The concrete cracking is simulated by the finite element method combined with the
constitutive model based on the nonlinear fracture mechanics. The model uncertainties for …

In this work, a refined interelement diffuse fracture theoretical model, based on a cohesive
finite element approach, is proposed for concrete and other quasibrittle materials. This …

The paper presents the results of a numerical analysis (FEM) describing the effect of the
undercutting head angle on the formation of the rock mass failure zone during the initial …

In this paper, a new model for chloride diffusion in cracked concrete is presented. The model
was developed within a standard continuum damage mechanics framework but newly …

We present a method of simulating the cohesive fracture behavior of reinforced concrete.
The proposed method achieved a satisfactory correspondence with the experimental results …
