Original Abstract

The contribution introduces 2D and 3D discrete static model of concrete based on Voronoi tessellation. Attention is focused on the boundary region where, due to presence of boundaries, the orientation of contacts exhibits strong bias. The bias has consequences in mechanical behavior of the boundary region in both elastic and inelastic regimes. The boundary layer is typically weaker and more brittle compared to the interior and also stiffer or more compliant depending on macroscopic Poisson's ratio and straining direction.
