The transient problem of deceleration and arrest of a rapidly propagating crack tip has been investigated for a crack which initially propagates in an elastic solid but then enters a region of viscoplastic material properties. The governing equations have been solved numerically by a finite-difference procedure. Arrest of a crack in a perfectly elastic material has been treated as a special case. Field quantities such as the effective plastic strain, the stress in the plane of the crack, and the crack face displacement have been computed, and the relation to arrest criteria has been explored.
