Computer Simulation of Ultimate Strength Degradation of Ship Structures by Corrosion and Fatigue
Current ship structure strength assessment procedures used by ship classification societies are mostly experience-based. The degradation effects of damages including fatigue, corrosion, collision and grounding on ultimate strength are seldom taken into account. Cui and Wu [1] proposed a more rational ship structure strength assessment method, First-Principle-Based Strength Assessment System (FB...
متن کاملLocal slamming impact of sandwich composite hulls
We develop a hydroelastic model based on a {3,2}-order sandwich composite panel theory and Wagner’s water impact theory for investigating the fluid–structure interaction during the slamming process. The sandwich panel theory incorporates the transverse shear and the transverse normal deformations of the core, while the face sheets are modeled with the Kirchhoff plate theory. The structural mode...
متن کاملA Review on the Drag Reduction Methods of the Ship Hulls for Improving the Hydrodynamic Performance
Hydrodynamic performance of a marine vessel mainly depends on the frictional and pressure resistance. Pressure drag reduction could be achieved by improving the shape of the vessels with implementation of modern hull forms. Hull forms optimization techniques could also be used for this purpose. Other techniques are needed to deal with the viscous portion of the total resistance, which is mainly...

متن کاملAn Adjoint Method for Design Optimization of Ship Hulls
We present a design optimization method for reducing the wave resistance (drag) of surface piercing hulls. Since this component of the drag is directly related to the energy contained in the wave structure that extends behind the ship, a fully coupled calculation of the flow field and wave evolution equation is required. The method combines the authors’ efficient automatic shape optimization te...
