Abstract
Higher order Mode-I elastodynamic fields at the tip of a
crack are calculated by the perturbation method. We use a certain condition
at the crack tip as one of the boundary conditions and resolve the
difficulty encountered otherwise [1]. We find that the well-known hoop
stress maximum at the crack velocity, 60 % of the transverse sound speed,
disappears when the crack is accelerated.
