This paper is concerned with the influence of dynamic effects on the conditions for initiation, unstable growth and arrest of crack propagation. The general form of the near-tip elastodynamic fields is discussed, and elastodynamic singularities are accommodated within the context of the energy criterion for fracture. The influence of material behavior, including plastic flow, on near tip fields is examined. Directional stability of a rapidly propagating crack tip is also discussed.
