✦ Synopsis

The steady-state problem of a semi-infinite shear crack propagating with a velocity greater than the shear-wave velocity was considered. The crack was modeled by a straight cut which extended in its own plane under the action of in-plane shear stresses uniformly distributed over a segment of the crack lips. In this paper we were particularly interested in the stress singularity which was found to be different from that corresponding to the subsonic case. Complex variable methods have been employed exclusively.
