Solid Electrolyte Crack-Driven Dendrite Shorting

Solid-state battery electrolytes don't fail the way liquid ones do — instead of a dendrite squeezing through free liquid, lithium metal wedges into a pre-existing microscopic flaw in the ceramic and forces it open, crack by crack, until it bridges the electrolyte. This simulator models that fracture-mechanics competition directly: an electrochemical wedging stress driven by your plating current pushes against the electrolyte's fracture toughness at a flaw of a chosen starting size, and applied stack pressure pushes back. Watch the stress-intensity factor and crack length update live as you tune the four parameters, and see the crack self-arrest at a stable length or run away to a short circuit exactly as the Griffith criterion K = σ√(πa) predicts.
