3D mesoscale finite element modelling of concrete (2017, unknown): “A modified version of the ellipsoid function [11] made it possible to better approximate real aggregates.”
Numerical Evaluation of the Influence of Aggregates on Concrete Compressive Strength at High Strain Rate (2011, unknown): “INFLUENCE OF ITZ ON CONCRETE COMPRESSIVE BEHAVIOUR Some previous studies [20, 41, 44] neglected ITZ because it is very difficult and extremely time consuming to include ITZ in the model, and because the material properties of ITZ are not well understood yet.”
Application of time reverse modeling on ultrasonic non-destructive testing of concrete (2011, unknown): “A numerical concrete model in 2D with randomly distributed concrete constituents similar to [17] is presented (Fig.”
On the effect of ITZ thickness in meso-scale models of concrete (2020, background): “and mortar [8,9], as a three-phase composite with the addition of interfacial transition zones (ITZs) between aggregates and mortar [10–13], and more recently as a four-phase composite with the addition of inherent defects such as voids and pores [3,14–17].”
