Advanced Mechanics of Maritime Structures

The course 'Advanced Mechanics of Maritime Structures' focuses on the response of ship and offshore structures subject to torsion. The loading of maritime structures generally consists of normal and shear forces, as well as bending and torsion moments. Torsion becomes particularly important under staggered cargo loading conditions and when operating in quartering seas. These conditions introduce shear strain and stress, as well as normal strain and stress responses in the structural members. To effectively establish and calculate the torsional response of marine structures, the course covers the following subjects:

Free Warping Torsion: Beam Stiffness and Strength Characteristics

• Solid Cross-Sections: Saint-Venant theory

• Hollow Cross-Sections:

• Thin-Walled Open: Membrane analogy

• Thick-Walled Closed

• Thin-Walled Closed: Single-Cell (Bredt approximation)

• Thin-Walled Closed: Multi-Cell

• Thin-Walled Mixed (Hybrid)

Free Warping Torsion: Beam Displacements

• Solid Cross-Sections

• Hollow Cross-Sections

Constrained Warping Torsion: Beam Shear and Normal Stress

• Hollow Cross-Sections: Thin-Walled Open

• Hollow Cross-Sections: Thin-Walled Closed

Generalised Torsion Equation

• Hollow Cross-Sections: Thin-Walled Open

• Hollow Cross-Sections: Thin-Walled Closed

• Monitoring of Maritime Structures Subject to Torsion
