Description
Xiaonian Chen and colleagues simulate how concrete crushes under load when its stones are jagged polygons, in a 2026 study. Real concrete stones are angular, not round, and their shape steers where cracks start and how the block fails. The team wrote a program that scatters random polygons through a virtual block and sorts each particle by role, stone, mortar, or seam.
A smooth particle method then squeezed the blocks in a press simulation. More stones, or a wider size spread, turned single shear cracks into diffuse damage and made the block more brittle. More edges per stone did the reverse, spreading fine cracks and adding give. Failure shapes matched published results well, backing the tool for studying mix design before casting real blocks.
