This Ship Structure Committee project was developed to demonstrate the fracture susceptibility of a ship structure. This demonstration was intended to illustrate the application of failure assessment technique and how these analysis techniques could be used to aid ship owners and operators in evaluating the susceptibility of their vessels and thus support maintenance activities. It is proposed that the potential applications could, in the future, be extended to the improvement of vessel design and maintenance practice. Some applications could include inspection focusing, repair prioritization, identification of critical details, and gauging the significance of each structural member. The report presenting the results of this project includes a description of the analysis approach and provides background on key elements of the supporting data and analysis techniques. Based upon this review, this demonstration project assembled sample material data, vessel loading, a failure criterion, and developed flaw location and size scenarios. The demonstration considered various fracture toughness levels, residual stress levels, and locations within the vessel on failure probabilities.
