🏗️ Wrecking Ball Physics: Impact Energy, Voronoi Fracture and Wall Demolition

Swing a crane-suspended wrecking ball (exact large-angle pendulum with the elliptic-integral period) into pre-fractured brick, 3D-Voronoi concrete, glass or an empty concrete frame building. Pieces are rigid bodies joined by breakable bonds that fail at a stress limit; a live ledger splits the ball's energy into kinetic, gravity, Griffith crack-surface and dissipated parts, with fragment-size statistics and progressive collapse. Differs from the existing wrecking-ball and Voronoi-impact pages by the checked energy partition (Gc times crack area), the fragment size distribution, the multi-storey progressive-collapse scenario and measured-vs-formula tests of period, momentum and energy balance. Inanimate targets only.
