Abstract

This work investigates the process of fatigue crack initiation in the structural joints of a dry cargo ship. The study addresses problematic issues related to changing the durability of the joints in the intersection of the longitudinal stiffener of the bottom and the floor, as well as the intersection of side structures and the double bottom along the length of the dry cargo ship.

Underlying the study is a simplified approach to determining external loads, the finite element method, the linear fatigue damage summation hypothesis, as well as the nominal stress approach.

Scientific ideas have been deepened about the regularities of changes in the parameters of the long-term load distribution on structural joints along the length of the dry cargo ship. The distribution scale parameter was taken as the criterion in the calculations. For the joint in the intersection of the longitudinal stiffener of the bottom and the floor, the distribution scale parameter increased when moving from the middle compartments of the ship to the bow by 5% for the loading condition "fully loaded vessel" and was unchanged for the loading condition "ship in ballast". For the junction of the bottom and frame structures, this parameter increased by 11–12% for the loading condition “fully loaded vessel” and by 11.8–13.7% for the loading condition “vessel in ballast”.

It was established that the durability of both joints decreases from the middle part of the hull to the bow as follows: the junction of the longitudinal stiffener of the bottom and the floor – by 21%; the junction of the frame with a double bottom – by 42%.

The results are explained by the determining influence of local loads in the bow of the vessel. They could be applied in the field of shipbuilding and ship repair when designing dry cargo vessel structures and when planning hull condition inspections
