Design and analysis of hybrid titanium-composite hull structures under extreme wave and slamming loads

A finite element tool has been developed to design and investigate a multi-hull
composite ship structure, and a hybrid hull of identical length and beam. Hybrid hull
structure is assembled by Titanium alloy (Ti-6Al-4V) frame and sandwich composite
panels. Wave loads and slamming loads acting on both hull structures have been
calculated according to ABS rules at sea state 5 with a ship velocity of 40 knots.
Comparisons of deformations and stresses between two sets of loadings demonstrate that
slamming loads have more detrimental effects on ship structure. Deformation under
slamming is almost one order higher than that caused by wave loads. Also, Titanium
frame in hybrid hull significantly reduces both deformation and stresses when compared
to composite hull due to enhancement of in plane strength and stiffness of the hull.
A 73m long hybrid hull has also been investigated under wave and slamming loads in time
domain for dynamic analysis. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2013.
