Abstract or Summary
  • In this paper, a numerical method is used to predict the response of an elastic body during a collision in which both normal and tangential impulses are important. Results are compared with those from simplified prediction procedures, which stem from the assumptions that the energy-returning capacity of the normal deformation mechanism is constant and the tangential compliance is neglected. The finite-element predictions indicate the importance of the tangential compliance for elastic collisions wherein friction forces are significant. The results of both methods of prediction point up the roles of friction and inertia coupling in determining the normal velocity ratio (the "coefficient of restitution").
