TL;DR: In this paper, a 3D meso-scale finite element model of concrete based on in-situ X-ray Computed Tomography (XCT) images is developed and validated.

TL;DR: In this article, the authors investigated the dynamic damage and fracture behavior of concrete under compression with strain rate up to 100 ǫ s−1 by Monte Carlo simulations (MCSs) of realistic meso-scale models based on high-resolution micro-scale X-ray computed tomography (XCT) images.

TL;DR: In this paper, Monte Carlo simulations of realistic meso-scale models based on high-resolution micro-scale X-ray Computed Tomography (XCT) images, using asymptotic homogenization and the concrete damaged plasticity (CDP) model, were used to characterize mesoscale mechanical behaviors of concrete.

TL;DR: In this paper, the authors developed a method coupling the finite element method (FEM) and the scaled boundary finite element (SBFEM), for efficient meso-scale fracture modelling of concrete for the first time.

TL;DR: In this paper, a simple algorithm is devised to discretize samples into meshes consisting of semi-analytical scaled boundary finite element (SBFE) polygons only, where each aggregate is modelled by one SBFE polygon and only polygonal boundaries are discretized into nodes.
