Measuring Quasi-Static and Kinetic Coefficient of Restitution   Simultaneously using Levitation Mass Method: Experiment and Simulation
  Observed peaks in a levitation mass method (LMM), which are usually addressed to signal noise, are discussed in this work. This phenomenon arises due to bounce from plate which is collided by moving part in LMM measurement system. Normally, the moving part and the plate stick very good after their first contact. Simulation using molecular dynamics (MD) method is performed to prove the bounce prognosis.
