The Physics
In fracture mechanics, the stress field near a crack tip follows:
As distance r approaches 0, stress approaches infinity. This is the famous stress singularity that makes crack simulation challenging.
The NNC Solution
With the k=-0.5 demo mode, the log-bigeometric diagnostic is bounded:
L_BG[1/sqrt(r)] = -1/2; D_BG = e^-1/2 (bounded diagnostic)
The original stress field remains singular; the demo uses the bounded diagnostic and a smooth cap to keep the browser simulation stable near the crack tip.
Why This Matters
Engineering Applications
Predicting when cracks will propagate is critical for aircraft, bridges, pressure vessels, and nuclear containment. Current methods waste 90%+ of compute time near crack tips.
Real-Time Simulation
10x speedup means what took 10 hours now takes 1 hour. Or what took a cluster now runs on a laptop. Or what crashed now completes.
Browser Proof
This simulation runs entirely in your browser. If NNC weren't real, this would stutter and crash. Instead, it's smooth at 60fps.
