Many researchers have studied the impact phenomenon in ball games, such as golf, tennis, baseball, soccer and so on. Although it is very important to understand the dynamic behavior of a ball on the impact phenomenon, the sufficient theoretical understanding of the behavior has not been obtained. In this paper, dynamics of hollow balls subjected to axial impact is theoretically analysed and the dynamic response of hollow balls is derived as an axisymmetric motion of an elastic spherical shell by using modal expansion method, where effects of area applied by impact force are took into account. The modal distribution of mechanical energies resulted by the work of half-sine axial impact force distributed uniformly in limited area are discussed.
