Numerical comparison in 2D/3D discrete concrete models shows Tessellation BCs yield well-defined localization bands fixed by model geometry, unlike Percolation-path-aligned BCs which suffer from uneven straining and spurious localization.

On representation of macroscopic crack in periodic fine-scale discrete mechanical models
Numerical comparison in 2D/3D discrete concrete models shows Tessellation BCs yield well-defined localization bands fixed by model geometry, unlike Percolation-path-aligned BCs which suffer from uneven straining and spurious localization.
