The effect of mesh density in lattice models for concrete with incorporated mesostructure

Original language description

This paper shows that mesh density dependency in brittle element lattice models cannot be completely removed by incorporating material mesostructure. This is concluded as a result of a series of simulations of fracturing in concrete using a 2D rigid-body-spring network. In the case of notched beams loaded in three-point-bending (TPB), adding finer grain structure led to a significant reduction in the dependency of the peak force on the mesh density. However, the energy dissipated during the fracture simulation was still affected significantly by the mesh density.
