Monazite Fracture Analysis: Stress-Intensity Crack Propagation (2D)

2D fracture-mechanics lab: linear-elastic stress-intensity factor and sub-critical stress-corrosion crack growth drive a monazite grain toward its Griffith-Irwin critical crack length, then an unstable burst shatters it — the same physics behind ore comminution and rare-earth mineral liberation.

This 2D companion strips the 3D rare-earth extraction scene down to the fracture mechanics that actually govern ore breakage: a real edge-crack stress-intensity formula (K_I = Y·σ·√(π·a)), a sub-critical stress-corrosion crack-growth law that ties directly to the fracture-toughness slider, and a Griffith–Irwin instability — once the crack reaches its critical length the equilibrium flips unstable and the grain shatters in a fraction of a second, exactly as brittle ore does under a crusher jaw. A live K_I/K_IC sparkline and numeric readouts (stress intensity, crack length, energy release rate, cycle count, fragments produced) make the otherwise invisible approach to failure directly visible and controllable, tying the same comminution physics back to why monazite needs to be cracked open before its rare-earth-bearing lattice can be liberated for extraction.
