Compare contact and rebound of falling spheres
Compare sphere indentation, contact duration and rebound under gravity. Enter effective contact modulus, mass, radius, drop height and loss for a Hertz-type approximation.1× means real time.

These are assumed input examples, not product or material test data. A is the reference and B the comparison. Mass, size and drop height are shared.
Inspect the motion
Top: whole sphere. Bottom: contact region enlarged12×. A/B share time and length scales. The equivalent model uses a rigid sphere and an elastic half-space.

Set the conditions
Modulus and loss are not inferred from Shore hardness. For the rigid-sphere model, E* is the surface modulus E/(1−ν²). A helper below can calculate it.
