ABSTRACT
Concrete is widely used but limited by its brittle behaviour and low tensile strength. Fibre-reinforced concrete (FRC) improves crack resistance, ductility, and tensile performance, yet its microstructural mechanisms remain insufficiently understood. This study uses the DEM code YADE to model concrete as a two-phase material and analyse the pull-out behaviour of fibres. Fibres were represented with real geometry, either rigid or deformable. Simulations were compared with experimental data, highlighting the role of interface stresses, and fibre deformability. The results demonstrate DEM’s effectiveness in capturing fibre-concrete interaction.
