Atherosclerosis is a progressive arterial disease in which fatty tissue accumulates in the arterial wall. Due to this lipid uptake, the artery thickens and can eventually rupture, causing the lipids to flow into the bloodstream and form blood clots. If this happens in the carotid arteries, which supply the head with oxygenated blood, a stroke...

The safety of a commercial aircraft is a factor to consider from the early stages of its design to guarantee that this one's structure can protect the occupants inside in a low-speed crash. In an aircraft's primary structure such as a fuselage, where the occupants and cargo should be protected, the design regulations imposed by the EASA have...

Reliable and efficient modelling of magnetic hysteresis in inhomogeneous and aniso-tropic media is an important step in developing a state-of-the-art closed-loop degaussing system for naval ships and submarines, to be developed by TNO and to be used by the Royal Netherlands Navy in an updated generation of naval vessels and submarines. Different...

One result of climate change is the increasing strength and frequency of wind events. This creates a problem for the also increasing number of high-rise buildings many of which are of unconventional shape. However, current methods for calculating wind response either do not account for these geometries, such as the Eurocode or are prohibitively...

In finite element analysis, nonlinear time-history analysis is a realistic and accurate analysis type for dynamic or seismic analysis due to its solutions contain wealthy data and complete response time-history. The most commonly used method, probably the only practical procedure, in nonlinear time-history analysis is the direct time integration...

Engineering fields such as aerospace rely heavily on the Finite Element Method (FEM) as a modelling tool. In combination with the scale and complexity of the structures typically involved here, computational cost remains a traditional issue. To perform FEM analyses of such structures efficiently nonetheless, engineers rely on techniques such as...

One way to implement a wind turbine in the sea is to use lattice structures. Since these structures are placed offshore, they must be able to withstand all kinds of loads. It is essential that the eigenfrequencies of the support structure do not correspond to the passing frequencies of the blades and any other dynamic actions. To avoid this the...

The Finite Element Method is used in many computer programs to analyse the mechanical behaviour of shell structures. Although this method provides good quantitative insight into the mechanical behaviour of shell structures, it provides little qualitative insight. This master graduation thesis is aimed at expanding Finite Element Analysis (FEA)...

Delamination is one of the failure modes of composites prone to happen in the case of a car crash. In the early stages of car design, finite element analysis is used as a tool to analyze structural concepts. In order to model delamination in a newly developed material model, it is analyzed in two parts: detection and effects of delamination. To...

The Europa Lander is a mission by NASA to land scientific instruments on the Jovian Moon by 2030. The current design of the landing system envisions fixed landing legs with the lander being lowered down at very low velocities (≈ 0.1 m/s) by use of a Skycrane. This latter system not only adds mass, but also requires complicated moving parts and a...

Over the past decades an increase in underground construction is observed. Deep excavations are among the structures used for underground construction. The construction of such structures often affects nearby existing structures and causes possibly even damages.<br/>The prediction of these damages is usually done by following these steps:<br/>1....

An accurate corner strength modelling method is required at Fokker Aerostructures to design canisters (missile launch tubes) with rounded corners for an internal pressure load case. To this end a combination of experiments and calculation methods has been developed that enable to predict the corner strength more accurately. Internal pressure...

This master thesis covers the research into cracking behaviour of slender high strength concrete cantilevering balconies. The research emerged from Pieters Bouwtechniek Delft and Hi-Con Denmark. They cooperatively designed very slender balconies in ultra-high performance fibre reinforced concrete. Other engineering firms tend to recreate these...

Orthotropic steel decks are widely used in bridge construction nowadays, especially in case of long span bridges. One of the main problems of bridges that utilize this technology is the susceptibility to fatigue failure. Cyclic loading due to wheel loads, in combination with the complex network of welded details, make such types of decks prone...

A novel continuum damage mechanics model for 2D woven fabrics has been developed and implemented in a VUMAT subroutine for Abaqus/Explicit. The model takes into account the shear non-linearity, the toughening mechanisms associated to tensile failure, and the influence of shear stresses in the initiation and propagation of tensile damage. <br/>...

Seafox owns and operates a fleet of 12 Jack-ups. The design life of these Jack-ups is typically around 30 years. However, some have remained operational after exceeding their design life. It is therefore critical to gain an understanding how long and under what conditions these jacks-ups are still able to operate safely. There are two main...

The numerical simulation of brittle failure with nonlinear finite element analysis (NLFEA) remains a challenge due to robustness issues. These problems are attributed to the softening material behaviour and the iterative nature of the Newton-Raphson type methods used in NLFEA. However, robust numerical simulations become increasingly important,...

At a time when there is a distinct drive for accelerated sustainability the Flying V is a promising new aircraft configuration with the potential for significantly higher efficiency than the current state-of-the-art. Up until this point the Landing Gear layout has only been investigated at an aircraft-level meaning there is limited knowledge on...

The research concentrated on a behavior of the deep composite deck ComFlor210 under a concentrated force. The distribution of a concentrated force in ComFlor210 was studied numerically and analytically. <br/>The finite element model of a composite slab with 5.4m span showed good agreement with test results in the elastic stage. The parametric...

Pile tip damage due to impact with an object (boulder) during the driving process of monopiles is of main concern in the offshore wind sector. Numerical modelling could accurately describe this failure mechanism and used as a tool in practice but also for the development of appropriate guidelines. In this research project, dynamic Finite Element...
