The axisymmetric problem of unsteady disk crack propagation in a transversely isotropic medium is solved. The general problem of dynamic crack motion under the action of given loads is made to close by introducing a fracture criterion. Estimates are presented for the displacements in unloading waves emitted by the growing crack. The results obtained can be utilized to set up a quantitative relation between acoustic emission pulse parameters, the characteristic crack dimension, and the velocity of its motion.
