In this article a finite element model is developed to study the oblique soccer ball bounce. A careful simulation of the interaction between the ball membrane and air pressure in the ball makes the model more realistic than analytical models, and helps to conduct an accurate study on the effect of different parameters on the ball bouncing. This finite element model includes surface-based fluid cavity to model the mechanical response between the ball carcass and the internal air of the ball.An experimental setup was devised to study the ball bounce at soccer gamerelevant impact conditions. The ball speed, angle and spin were measured before and after the bounce, as well as the ball deformation and the forces during the impact. The finite element model has been validated with three different test data, and the results demonstrate that the performed finite element model can be a valuable tool in the study of ball bounce. After validation of the utilized finite element model, the effect of the friction coefficient on soccer ball bounce was studied numerically. Simulation results show that increasing the friction coefficient may result into reversal of the horizontal impact force.
