Abstract
The connection between longitudinals and transverse web frames, is
a weak point in the fatigue strength of a ship structure. Moreover
it is very expensive to repair fatigue damages in these
intersections, and a fatigue analysis for a specific detail was
therefore carried out in order to seek to improve the design. A
new improved slot for the longitudinal intersection in the web
plate is found on the basis of a shape optimization of the
conventional slot. The new slot has an unique shape (tongue form)
resulting in a stress relaxation around the slot. Both the
conventional and the new slot structure were analyzed by FEM
followed by fatigue life calculations and subsequently compared.
The overall expected fatigue life for the shape optimized slot
will increase by approximately 12 %. The results were compared
with an another study concerning a slot for a T-longitudinal.
