The city of Amsterdam has a large number of old quay walls with rotten foundation piles. These foundation piles need to be identified and measures need to be taken. The urban quay walls are supported by two types of foundation: pinewood piles, which are easily affected by bacterial decay and spruce piles. To understand the mechanical behaviour...

This work aims at predicting the elasto-plastic and fracture behavior of ABS polymers obtained by Fused Filament Fabrication (FFF). The strategy adopted is to characterize the microstructure of Representative Volume Elements (RVEs) of the material, as well as the mechanical properties of the polymeric filament used in the FFF process and then...

Airborne Composites Automation recently installed an automation product line that creates flat thermoplastic laminates intended for consumer electronics industry. However, due to the composite nature of the material and the process parameters, the final product is deformed, as a result of internal residual stresses. The purpose of this thesis is...

Since the exploitation of wind as a renewable energy resource, jack-up vessels equipped with more than three independent legs are increasingly employed to transport and install the components of offshore wind turbines. By lowering the movable legs the vessel is able to elevate the hull from sea water level. In elevated position the vessel...

Quadrangular Grid shells have generated interest in recent years for their application in rationalizing free form geometry in the built environment. Shell structure are efficient because their form is governed by flow of internal forces. But while discretizing shells into grid shells, instead of using flow of forces, current method follows...

Background: Patients who suffer from acetabular bone defects are often subjected to a decreased mobility and a loss of independence. To treat these bone defects, standard hemispherical acetabular implants offer in most cases the solution. However, when these defects are large, a custom triflange acetabular implant is needed. Although this type...

In the framework of the High Luminosity LHC project at CERN, the need for further incorporation of evaluation of radiation damage into the design of beam intercepting devices at CERN is described and the risks of radiation damage in high energy applications are summarized. Radiation damage can be an important topic in high energy applications...

The Ishikawa concrete drying shrinkage model is a new computational model which simulates drying shrinkage behavior based on the theory of capillary pore pressure, a known drying shrinkage mechanism. Its initial validation against shrinkage tests shows promise. If the mathematical model can be further validated, it has potential to improve...

Majorana zero modes have been proposed as building blocks of intrinsically fault-tolerant quantum computers. Currently, externally applied magnetic fields are necessary to induce Majorana zero modes in carefully engineered systems. Topological qubit state readout is realized by parity sensing of Majorana islands. However, fast and high fidelity...

For the fatigue assessment of welded structures, several design methods are described by the design codes of IIW, Eurocode3 and DNV. The relation between the stress range and cycles to failures were derived from experiments: the SN curves. With the increased accessibility of finite element software to engineers, a more flexible approach emerged:...

A new linear sandwich shell element is presented, based on the third order shear deformation theory from Reddy in combination with a `zig-zag' model. Following from a set of benchmark tests, the sandwich element shows superior accuracy in determining facesheet stresses compared to the Abaqus S4 shell element and a good correlation with 3D finite...

Fracture mechanics based computational methods are becoming increasingly important to study the structural integrity and failure of materials and structures used in engineering applications. One challenging aspect for computational methods is the analysis of crack nucleation and propagation in complex geometries or in materials with...

This thesis continues the work performed by Ferreira and Almeida on the topic of weight and cost reduction of composite multi-spar torsion-bending boxes. The goal is to find the influence of changes to the structural configuration on the resulting weight of said torsion-bending boxes. Using analytical methods, combined into the BoxSolver MATLAB...

This master thesis presents research into buckling of thin hyperboloid shells structures. This type of structure is typically applied as the large cooling towers at coal fired electricity plants. However, modelling cooling towers is not the objective of this research. The objective of this research is to understand the buckling behaviour of...

Submarine pipeline is an important part of offshore oil and gas projects for fluid transmission purpose. Installation of pipelines, especially in deep water, can induce rather severe loads to the structure and this can lead to the unforeseeable risks and challenges. During pipe laying by vessel and reel ship, the pipe bend in the vertical plan...

As fossil fuel reserves are rapidly being depleted, sustainable alternatives have to be found to fulfil the world's energy demand. Numerous concepts have been proposed to generate electricity by harnessing renewable energy sources such as solar or wind power. One of these concepts is the the so-called solar updraft tower (SUT). The SUT consists...

This thesis studies the buckling behavior of I-shaped steel columns under the effect of thermal gradients. The mechanical properties of steel decay signicantly with increasing temperature. Therefore, in case of a re, the buckling resistance of steel columns is considerably reduced due to the decrease in the modulus of elasticity and yield...

In this work a Knowledge-Based Engineering approach is presented for validating the results of a semi-analytical weight estimation method used for the conceptual design of conventional and oval fuselages structures. The validation of these results is carried out by comparing the structural component's line loads as calculated by the semi...
