Abstract
Normal impact of hollow balls on flat surfaces is theoretically analyzed and the dynamic deformation of hollow balls is derived as an axisymmetric motion of an elastic spherical shell by using modal expansion method, where variation of contact area is taken into account. Numerical calculations were conducted and the dynamic characteristics are discussed. It is found that the center displacement of the ball possesses nearly a half-sine wave form while the reaction force has a triangular time history. It is also shown that the collision time decreases with increasing initial velocity of the ball. Verf.-Referat
