Protective Packaging Cushion Curve Simulator

Real protective-packaging engineers size a cushion pad using a "cushion curve" — a chart of peak impact deceleration against static stress for a given material and thickness. This simulator runs that same physics live in 3D: choose a drop height, a product mass, a cushion material and thickness, then drop the product and watch a nonlinear spring-damper model compress the pad exactly as a real foam, molded-pulp, honeycomb or air-pillow cushion would, reporting peak G-force, energy absorbed, maximum compression and the material volume used. Push the fragility threshold and thickness against each other to find the thinnest, lowest-volume cushion that still keeps the product's peak deceleration under its fragility rating — the central design trade-off behind minimal, eco-friendly packaging.
