Original Abstract

The discrete meso-scale model developed for simulation of concrete behavior with geometry based on Voronoi tessellation is studied. It is shown that the model exhibits geometrical bias in a boundary region due to modification of the tessellation when the boundary is present. The geometrical bias the the boundary layer further influences elastic and inelastic model behavior. The boundary layer effects are analyzed by simulating concrete prisms under tension (in elastic regime) and three-point bending (in inelastic regime). The results demonstrate that the the boundary layer becomes stiffer for positive and more compliant for negative Poisson’s ratio. In inelastic regime, the boundary layer is weaker and less ductile compared to the interior of the domain.
