✦ Synopsis

The asymptotic stress and displacement fields of a propagating interface crack under mode III conditions are determined by using the eigenfunction expansion technique. It is found that the well-known square root singularity is unchanged. A moving interface crack of constant length with constant speed is used as a simple illustrative example. In addition, the relationship between dynamic energy release rate and stress intensity factor is also derived in this communication.
