Abstract

This paper reports the investigation of steady-state elastodynamic frictional contact responses of a rigid or elastic indenter sliding on an elastic layer-substrate system at a sub-Rayleigh velocity. The developments of the elastodynamic frictional contact model include the analytical acquirement of elastodynamic frequency response functions by utilizing the Galilean transform and Fourier transform, and numerical implementation of contact pressure determination by adopting the conjugate gradient method. The stress and the displacement fields are calculated with the discrete convolution-fast Fourier transform algorithm. The detailed parameter analyses are provided to investigate the combined effects of the system parameters on the contact behaviors. The results indicate that the elastodynamic effect results in a softening contact response, which is more significant for stiffer layer cases.
