Ship-Monopile Interaction in combination with Lashings and Friction contacts

The increasing demand for renewable energy sources, to achieve ‘green goals’ such as the Paris agreement, and their related projects, are becoming increasingly challenging to accomplish. Nowadays, offshore wind farm projects move into deeper waters and require larger individual Offshore Wind Turbines<br/>(OWT’s), which results in larger...

Non-linear block load corrections for dry docking

Damen is designing more and more slender hull forms, which leads to a small dock block contact area, and therefore a high load on the block bed. Dry docking is achieved by using multiple blocks located along the longitudinal length of the ship. Dock blocks are constituted by several layers, normally three or more. The configuration of the block...

Improving the accuracy of analytical relationships for mechanical properties of permeable metamaterials

Permeable porous implants must satisfy several physical and biological requirements in order to be promising materials for orthopaedic application: they should have the proper levels of stiffness, permeability, and fatigue resistance approximately matching the corresponding levels in bone tissues. This can be achieved using designer materials...

Locking free discontinuous nonlinear thin-walled structures

The demand for using thin-walled composite structures for instance, in aircraft and ships are rising in the industry. These structures contain material interfaces, and at these interfaces, the structure exhibits non-smooth field behavior which is known as weak discontinuity. It is essential to study the effects of such discontinuities on the...

Steering towards Stiffness: A preliminary analysis method for local deformations in a yacht structure caused by wave-induced loads

The superyacht industry faces an increasing trend of larger dimensions, more open spaces, larger hull openings and more exotic shapes. This puts more effort on the structural design and especially for superyacht longitudinal stiffness is important, since the luxurious interior and delicate systems installed in a superyachts are not allowed to...

Mechanical properties of additively manufactured octagonal honeycombs

Honeycomb structures have found numerous applications as structural and biomedical materials due to their favourable properties such as low weight, high stiffness, and porosity. Application of additive manufacturing and 3D printing techniques allows for manufacturing of honeycombs with arbitrary shape and wall thickness, opening the way for...

Eigenvalue analysis of the Timoshenko beam theory with a damped boundary condition

In this report an attempt is made to analyse how a damped Timoshenko beam is affected by an external force.
