...For the central impact of two bodies Hunt and Crossley [32], Lankarani and Nikravesh [34], and Marhefka and Orin [35] established: e ¼ 1 a _d0; a ¼ 2b 3k ð28Þ An important aspect of this model is that damping depends on the indentation....

...For contact damping, one can use the energy-balance to find a relationship between contact damping and the coefficient of restitution [32,34,35], although, inevitably, such a result is limited by the accuracy of the coefficient of restitution....

...Non-linear damping To overcome the problems of the spring-dashpot model and to retain the advantages of the Hertz’s model, an alternative model for energy dissipation was introduced by Hunt and Crossley [32]....

...Spring-dashpot model The impact is schematically represented with a linear damper (dashpot) for the dissipation of energy in parallel with a linear spring for the elastic behavior [9]....

...The coefficient of restitution depends on many elements, such as the geometry of the bodies in contact, the approach velocity, the material properties, the duration of contact and, possibly, friction [9]....

...The principal and most general study of this subject is due to Goldsmith [9], who measured the displacements of the impacting bodies, the duration of impact, the geometry of the crater and the stress waves generated by the impact....
