• In order to observe the rebound characteristics of a tennis ball and the effects on the hand, FEM simulations for tennis ball impact were performed using a solid string model at different coefficients of friction between strings (called string friction). The 3-dimensional models of the tennis racket were achieved in CATIA V5R18 according to the geometry of a full sized Wilson tennis. To be emphasized, the model of strings was made into interlaced solid string model but not simple wire model. All models were made meshes using HyperMeshS.O and FEM simulations were completed in ABAQUS V6.8-Explicit. The FEM analyses results revealed that it is necessary to use a solid string model instead of a wire string model in clarifying the dynamic characteristics of tennis racket and ball. Besides, the results also show that larger coefficient of friction between strings is benefit to control a ball but may injure elbow more easily.
