Abstract
A simple mathematical model for the stick-slip motion is introduced and the dynamic response of an elastic solid to a moving SH-source with the stick-slip motion is discussed. Its exact response is obtained in the form of an infinite sum of time-harmonic response. Each component in the summation has a parametric-like frequency, i.e. a combination of two frequencies, stick-slip motion and time-harmonic source magnitude. The Doppler frequency shift is extracted from each component response. Due to the presence of two velocity parameters, the mean velocity and the frequency of the stick-slip motion, the Doppler effects take place even if the source magnitude is constant, not time-harmonic. The response is shown in graphical forms and it is found that the lowest frequency component has the dominant contribution to the total response.
