Development of a model for predicting dynamic response of a sphere at viscoelastic interface: A dynamic Hertz model

Abstract A model for predicting the dynamic response of a sphere at viscoelastic interface is presented. The based on Hertz contact and in medium. In addition to elastic properties medium size sphere, considers density viscosity medium, damping oscillations due radiation shear waves. can predict not only effects mechanical physical amplitude excitation force displacement, but also these parameters shift resonance frequency. proposed be used identify materials, understand responses spherical objects interfaces practical applications.
