Deceleration (G) during impact versus time. Dashed line = product fragility.
Model: rigid body on an elastic-plastic foam cushion (plateau stress sigma, stroke 0.75 d) in series with the floor spring. Peak G about sigma*A/(m g); safe drop h = F s/(m g) - s (Mindlin 1945; ASTM D1596 cushion curves).
