Comparative study of the cutting shape from the reinforced elements on the ship body structure
In order to achieve a lighter ship hull, solutions are required regarding the mass reduction of the structural elements, which are part of the ship hull. In the development of the ship hull, besides the shell, there is another series of system elements, the transverse and longitudinal frames, which ensure the rigidity, the strength and the stability of the ship. Depending on the building system of the ship hull, these structural elements have a more or less preponderance in the total mass of the ship. In this study paper using Finite Elements Method will be presented a comparative study of different cutting forms through the reinforced frame elements, which are a part of the structure of the ship hull. On the end will be some conclusions regarding the opportunity of adopting one form or the other.
