To keep pace with increasing renewable energy penetration and consequent increase in inverter-based resources in the power grid, it is pertinent for present-day research to address the resulting drop in system inertia levels and its impact on frequency stability. With decreasing levels of inherent rotational inertia present in the system, any...

Functionally graded materials (FGMs) represent a new class of materials that consist of graded compositional and microstructural patterns allowing to tailor properties. Additive manufacturing (AM) or more commonly known as 3D-printing offers a paradigm shift in FGMs and engineering design due to its ability to produce components with complex...

This research focused on the question whether it is possible to predict the density of tropical hardwoods with acceptable accuracy based on drill resistance measurements. To assess the feasibility, the influence of the characteristics of the drill resistance measurement tool; the Resistograph® and the wood species have been investigated. With...

Fatigue cracks could occur in the material of offshore and marine structures that are cyclically loaded. These cracks occur due to the cyclic stresses induced by the waves causing premature failure. Monitoring these fatigue cracks using a wireless system gives the opportunity to guarantee the integrity of the structure without manual inspection,...

In the past decades the understanding of fracture of ductile material has increased substantially. Research has shown that the onset of fracture highly depends on the full state of stress inside the material. Better understanding of fracture resulted in more advanced and complex fracture models being conceived, allowing researchers to predict...

Citizens are increasingly using Open Government Data (OGD) and engaging with OGD by designing and developing applications. They often do so by collaborating in groups, for example through self-organized groups or government-induced open data engagement initiatives, such as hackathons. The successful use and engagement of OGD by groups of...

In order to save weight and reduce the impact on the environment, the aerospace industry keeps searching for strong and lightweight materials to reduce fuel consumption. A relatively new manufacturing technique made it possible to print nylon, reinforced with continuous unidirectional carbon fibres on a layer-by-layer basis and praised itself...

Research into multi-axial fatigue requires knowledge on the through time and thickness development of the propagating crack front. In order to provide this knowledge methods must be developed to monitor crack initiation and growth during a fatigue test. The acoustic emission method has been recognised as a possible means to this end. <br/...

The tie rods in the Duomo are structural elements, subject to monotonic loading and cyclic loading. Non-destructive testing is used to find cracks and determine their geometry. Lamb waves are applied to determine the presence of cracks in the tie rod and to estimate their positions. The cracks are located using eddy current testing. Finally the...

Because of its proven beneficial material properties, Alloy 617 is the most promising material for the use in pressurised steam boiler components subject to cyclic loads and temperatures that are increasing due to an improved process efficiency. The result of this research project is the successful expression of the material properties of Alloy...

The start-up and shut-down cycling of a heavy-duty truck engine leads to temperature and mechanical strain variations in the exhaust manifold, subjecting it to thermo-mechanical fatigue (TMF) damage. For the automotive manufacturers, it is essential to accurately predict the TMF lifetimes of the exhaust manifolds under service conditions. The...

The high levels of wind and wave loads on offshore structures make fatigue analysis a significant parameter that has to be taken into consideration throughout an offshore structure design. Steel tubular members are widely used in offshore (wind) industry due to their efficient structural behaviour. The welded connections between the different...

While governments and researchers often focus on the opening of data through open data infrastructures, the adoption and use of open data infrastructures has received less attention, despite the fact that this use should result in the envisioned benefits. This study aims to examine to which extent and by which factors the acceptance and use of...

Within this report, a process improvement framework is developed and applied in the case of the outbound Logistics process at KLM Engineering & Maintenance. The methodology proposed for the improvement of the process includes a synergy of three different, but related theories: Lean, Six Sigma and Engineering Design. The integration of their...

In 2008, Hurricane Ike devastated Bolivar Peninsula, narrowly missing the more heavily industrialized and populated areas in the region. In the aftermath of the hurricane, the Severe Storm Prediction, Education and Evacuation from Disasters (SSPEED) Center at Rice University in Houston, and Texas A&M University in Galveston (TAMUG) led...

Open data movement is gaining widespread attention and spans across a variety of sectors (public, private, academic and civil). The last ten years have seen significant progress in opening of access to government datasets (Davies, 2010). This openness of public data has brought several benefits as: great transparency, innovation and the rise of...

Bending of dual-phase (DP) steels has introduced new issues concerning the analysis by finite element (FE) modelling. During the investigation of the microstructure of a DP1000 steel, it is found that there is crack formation at lower bending angles and elongations than would be expected based on the forming limit curves (FLCs). The results of...
