Research Abstract	This study constructed finite element models of the foot and soccer ball, and examined the factors affecting the ball behavior in curve kick. The models were validated by comparing the results of the finite element analysis to those of the experiment. Simulations of the ball behavior were conducted using the finite element models. The simulation results indicated the following. The ball velocity is largely affected by the foot velocity immediately before impact but barely affected by the Young's modulus of the shoe upper and the coefficient of friction. The ball rotation is affected by the foot velocity immediately before impact and the coefficient of friction; however, these factors had no significant effect.
