Abstract

Risk based methods can be used to optimise None Destructive Examination (NDE) planning of new building ship hull structures. A key step in this method is estimation of failure probability of fabrication weld defects under fatigue loading. This is achieved through probabilistic fatigue and fracture mechanics assessment. In this paper probabilistic fatigue and fracture mechanics analysis of a butt weld for a ship deck plate is presented.
