Shear Strength Assessment of Ship Hulls

The primary aim of the study is to investigate the ultimate strength characteristics of ship hulls with large hatch opening subjected to vertical and horizontal, shearing forces . As part of this study, the finite element package ANSYS was used for the efficient analysis of the ultimate strength of ship hulls subjected to shear forces. Progressive collapse behavior of a typical container vessel under vertical shear force, and horizontal shear force was analyzed. For analysis full hull model between bulkheads was modeled. When vertical shear force is applied, failure is due to warping of side shells of the vessel and stressing of bilge and top side areas where as the failure by horizontal shear force is mainly due to the warping of bottom shells of the vessel and due to stressing of bilge area.
