Wave Radiation from a Stick-Slip-Like Moving Source

Abstract:

Article Preview

Waves generated by a moving source are discussed. Introducing a simple model for the stick-slip motion of the source, an exact response of SH-wave in an infinite elastic solid is derived. The response is composed of an infinite sum of time-harmonic wave with multiple frequency of the stick-slip motion and Doppler effects are derived from the far-field approximation. This shows that Doppler effects take place even if the source magnitude is uniform, not time-harmonic.
