Impact of an elastic sphere with an elastic half space revisited: Numerical analysis based on the method of dimensionality reduction
Lyashenko, Iakov A.; Popov, Valentin L.
An impact of an elastic sphere with an elastic half space under no-slip conditions (infinitely large coefficient of friction) is studied numerically using the method of dimensionality reduction. It is shown that the rebound velocity and angular velocity, written as proper dimensionless variables, are determined by a function of only the ratio of tangential and normal stiffness ("Mindlin-ratio"). The obtained numerical results can be approximated by a simple analytical expression.
