Abstract
The development of a Windows based framework to undertake probabilistic fracture mechanics studies is reported. The reliability method used in the program is Monte-Carlo Simulation method. The results of the computation of the program are stress intensity factor, reliability index and probability of failure. The probabilistic studies of cruciform welded joint containing Lack of Penetration (LOP) defect and T-butt geometry containing surface crack at weld toe are performed in both critical crack growth and fatigue problem. The results can be used as an indicator for assuring the safety of this particular type of connection. It can also be used as a design criterion for the connection.
