Abstract

Three-dimensional (3D) meso-scale finite element models of concrete in compression based on in-situ X-ray Computed Tomography (XCT) images are developed and validated in this study. The micro-scale images from a Brazilian-like in-situ XCT test are first compressed and then transformed into manageable meso-scale 3D meshes using a voxel hexahedron meshing technique with a stacking algorithm. The concrete damaged plasticity model in ABAQUS is used to simulate complicated damage and fracture behaviour of concrete. Excellent qualitative agreement is found between the simulations and the XCT test in terms of damage evolution and fracture process on both the surface and interior of the specimen. The effects of internal heterogeneous meso-structures on the macro-scale loading-carrying capacities and failure patterns are quantitatively and qualitatively evaluated by modelling different uniaxial loading directions.
