Abstract: This technical deep-dive explains how dual-density rubber pads and floating substructures convert kinetic energy into heat. Using finite element analysis (FEA) simulations, it visualizes stress distribution during a basketball dunk, showing how 12mm pads reduce peak forces by 55% compared to concrete. The article also debunks myths about “softer = better,” citing data that overly plush floors increase Achilles strain. A glossary of terms like “vertical deformation” and “area elasticity” aids non-experts.
Key Points:
- Hertzian contact theory applied to floor-shoe interaction.
- Comparison of natural rubber vs. SBR pads in humid environments.
- Role of panel joints (tongue-and-groove vs. click systems) in load transfer.
- ASTM F2772 standard’s four performance categories explained.
