Ice Sheet Fracture: Crack Propagation Lab (2D)

2D companion to the 3D Ice Fracture simulator: real fracture-mechanics rules drive a stressed ice sheet — stress concentrates at every crack tip (K = sigma * sqrt(pi * a)), tips branch once K crosses the material's toughness, and hard impacts shatter the ice into flying Voronoi fragments.

A 2D companion to the 3D Ice Fracture simulator: strike a stressed ice sheet and watch cracks grow, bend and branch under real stress-intensity rules, shattering into Voronoi fragments when the impact is strong enough.

⚙ Under the hood

A 2D companion to the 3D Ice Fracture simulator built on real fracture-mechanics rules: each crack tip carries a stress-intensity factor K = sigma * sqrt(pi * a), tips bend toward higher local stress, fork into branches once K crosses roughly 1.9x the material's toughness, and a hard enough impact shatters the ice into a true bounded Voronoi diagram of flying fragments.
