Six cases of damage tolerance assessment are presented, involving structures or vehicles in the U.S. transportation industry. Damage tolerance means arranging design, maintenance, and inspection practices to assure that growing fatigue cracks or cracks caused by foreign-object damage can be detected and repaired before they cause structural failures. Damage tolerance assessment involves the practical application of fracture mechanics principles to complex structures in complex service environments. Four of the six accounts involve specific assessments of service failures; the remaining two describe continuing efforts to embody the damage tolerance philosophy in design practices. The authors of each case study are principal engineers involved in the work reported.
