Concrete can be considered as a heterogeneous material at mesoscale comprising of
several constituents such as aggregates, mortar and Interfacial Transition Zone (ITZ) …

Further understanding of the mechanical responses and the failure mechanism of concrete
under different loadings, the mesoscale modelling approach considering the heterogeneity …

This study aims to evaluate the macro-micro-meso-mechanical properties of basalt fiber (BF)-
reinforced recycled aggregate concrete (BFRAC). Firstly, the effects of BF with different …

This paper presents a meso-scale modelling framework to investigate the fracture process in
concrete subjected to uniaxial and biaxial compression accounting for its mesostructural …

Abstract Three-dimensional (3D) meso-scale finite element models of concrete based on in-
situ X-ray Computed Tomography (XCT) images are developed and validated in this study …

The aggregate size plays an important role in the nonlinear mechanical behaviour of
concrete, which is strongly related to the size effect. In this study, the meso-mechanical …

Great progresses have been made in static size effect of concrete, while almost no efforts
have been conducted in dynamic size effect of concrete. The macro nonlinearity and size …

Methodology for analysis of meso-structure effects on longer-scale mechanical response of
concrete is developed. Efficient algorithms for particle generation and packing are proposed …

This work addresses a knowledge gap in meso-scale modelling of concrete–the effect of
selected computational ITZ thickness on predicted macroscopic behaviour. A novel …

The realization of approximate practical aggregate models is a crucial link to the mesoscopic
mechanical analysis for fully-graded concrete. This study systematically presents the …
