Abstract:

The propagation of a circular crack under dynamic torsional loading conditions is considered. The crack perimeter speed is taken to be an arbitrary monotonic increasing function of time. A general solution is obtained by means of integral transforms, together with Kostrovs technique particular results are extracted for an initial value problem and for a suddenly appearing crack problem. The dynamic stresses near the periphery of the crack are found to have an inverse square root singularity.
