A novel pathway to characterise footballs for finite element analysis

(Ein neuartiger Ansatz zur Charakterisierung von Fußbällen für die Finite-Elemente-Analyse)

This study developed a method to characterise materials used in football manufacture for finite element analysis. Quasi-static (0.1/s) and dynamic (10/s and 100/s) uniaxial testing on a FIFA Quality Programme approved football generated hyperelastic material coefficients. Dynamic mechanical analysis was utilised to create Prony series coefficients to inform the viscoelastic behaviour. The model was validated by comparing finite element simulations with experimental data, focusing on dynamic properties including coefficient of restitution, maximum deformation, and contact time. Results indicated a strong correlation, with RMSE between 0.0051 and 10.4310, particularly at 0.8 bar pressure, demonstrating the model`s efficacy for high-strain impacts. This research lays the groundwork for optimising football performance and investigating peak forces related to ball-player interactions.
