Buckling and ultimate capability of plates and stiffened panels in axial compression

Risk assessment of aging ship hull structures in the presence of corrosion and fatigue

The aim of this study is to derive a simple analytical formula for predicting the ultimate collapse strength of a single- and double-hull ship under a vertical bending moment, and also to characterize the accuracy and applicability for earlier approximate formulations. It is known that a ship hull will reach the overall collapse state if both collapse of the compression flange and yielding of the tension flange occur. Side shells in the vicinity of the compression and the tension flanges will often fail also, but the material around the final neutral axis will remain in the elastic state. Based on this observation, a credible distribution of longitudinal stresses around the hull section at the overall collapse state is assumed, and an explicit analytical equation for calculating the hull ultimate strength is obtained. A comparison between the derived formula and existing expressions is made for largescale box girder models, a one-third-scale frigate hull model, and full-scale ship hulls.

Ultimate strength analysis of a bulk carrier hull girder under alternate hold loading condition – A case study: Part 1: Nonlinear finite element modelling and ultimate hull girder capacity

Experimental assessment of the ultimate strength of a box girder subjected to severe corrosion

Literature related to recent work in predicting ultimate strength of a ship hull girder is reviewed and discussed. Instability factors are presented for determining the maximum load such a girder will sustain in the sagging mode. Two bibliography sections are included: one for ultimate load for box structures and the other for primary and secondary structure associated with ultimate strength.
