The purposes of this study are to construct FE models of golf balls with a hyper-elasticity and viscoelasticity and to devise a method for identification of the FE ball models by using the relation between material properties and the behavior of the golf ball during and after impact event which was reveal in this paper. As the material model of the FE ball model, the Mooney-Rivlin model and the three-element viscoelastic model were used. In the FEA, normal and oblique impacts were simulated. The impact load, deformations of the ball, rebound velocity, angle and spin rate were looked at and their effects on the behavior of the ball were investigated. Then, the method for identification of the FE ball model was created. Also, the impact experiment was carried out to obtain the dynamic properties of the golf ball. The solution of FEA was well-matched with the experiment by using the method and an application with another type of golf ball verified the method.
