Ultimate Strength Analysis of Ship Hull Girder Under Random Material and Geometric Properties
Keyword(s):
The ultimate strength of a ship’s hull depends on its material and geometric properties, some or all of which may be random in nature. In addition, initial imperfections in the form of the initial deflection and residual welding stresses in the plating between stiffeners, can significantly affect the hull ultimate strength. In this paper, the effect of randomness in yield strength, member thickness and in the initial imperfections on ultimate hull girder strength is determined. Different levels of statistical dependence between the yield strength and initial imperfection of all stiffeners and plating between stiffeners have been considered. The methodology is applied on a bulk carrier and a VLCC tanker.
