Kanninen, S. Hudak Jr., H. Couque, R. Dexter, P. O'Donoghue] The many practical situations in which the initiation of rapid crack propagation cannot be absolutely precluded and where the consequences of a large scale fracture would be catastrophic mandate the development and use of crack arrest fracture mechanics technology. Most currently applied procedures utilize linear elastic analyses and corresponding material fracture property characterizations. Even though the theoretical basis for the use of this level of approach is incomplete, selected practical applications are described in this paper that show that these can still be effectively made. In addition, to address the current deficiencies and to treat those conditions where small-scale yielding conditions are clearly not satisfied, more advanced viscoplastic-dynamic analyses are also being developed. An approach is described in this paper that performs well-instrumented fracture propagation experiments in concert with viscoplastic dynamic finite-element simulations. This approach, currently used to quantify critical values of the T * crack tip characterizing parameter developed by Atluri, is being pursued in order to provide transferable material crack arrest toughness values in the regime where viscoplastic-dynamic conditions dominate.
