Offerman, Maurice (author)Bipolar half plates (BPPs) are important parts of Proton Exchange Membrane (PEM) hydrogen fuel cells. Metallic BPPs are generally produced by stamping or hydro forming. However, these processes are not continuous and relatively slow compared to rotary forming. Rotary forming is a continuous process and could potentially be a faster BPP...master thesis 2022

Arens, Patricia (author)In the last decades there has been an increasing interest in computing the local strain at the atomic scale of materials. By knowing aspects of the local strain in a lattice, one has information about measurements of distortions of lattice parameters concerning shifts, deformations and defects computed with respect to a smooth, defect-free...bachelor thesis 2022

Huang, Stephen (author)Distance learning brings all sorts of advantages. The ability to follow lectures at home can save people transportation costs and time. Teaching through videoconferencing software such as Zoom is one of the methods to learn remotely. To explore new and better teaching methods, the possibility of using a telepresence robot is investigated. To...bachelor thesis 2022

de Heer, Izak (author)Surface corrugations in graphene negatively effect the unique and useful properties of graphene. In order to exploit the special properties of graphene, it is therefore important to understand the phenomenon of wrinkling. In this study, strain engineering was applied to study the flattening of wrinkles in a suspended graphene membrane. Initially...master thesis 2022

de Bles, Wouter (author)Fiber-reinforced composite (FRC) marine propellers potentially outperform metallic propellers in terms of efficiency and underwater radiated noise (URN) by hydro-elastic tailoring of the blades. Several methods can assess the extent of these potentials. Research shows that embedded sensing methods can be used in dynamic measurements of...master thesis 2022

Solbes Ferri, Irene (author)The objective of this master project is to improve the current SHM techniques for global damage identification of beam-like composite structures. The studied damage diagnosis method is based on structural vibrations from which the modal parameters are obtained. The literature study provides an overview of the most common vibration-based damage...master thesis 2022

Hengst, Madusha (author)Atherosclerotic plaque rupture is the underlying cause of 50% of deaths in western society. Although screening methodologies exist, plaques are highly complex, and the parameters used to measure plaque vulnerability are often insufficient for correct medical screening. Since plaque rupture occurs when the vascular forces exceed the plaque...master thesis 2021

Cleijpool, Bram (author)The detachment of a product from a suction cup gripper is a challenge that emerged in recent years in the high-speed case packing of packaged food. In this industry suction cups are used to temporarily attach a product to a case packing robot. The detachment of products from the suction cup gripper threatens throughput. In, some cases, the...master thesis 2021

Walrave, Niels (author)In the Netherlands the design condition for a dike is surmised to occur during winter where it is assumed that the dike is fully saturated. Preliminary results by Van Duinen (2020) indicate that suction remains present, albeit ever decreasing, during the winter. This means that it would be possible for a dike to dry out during the summer period...master thesis 2021

Spinatelli, Vieri (author)The on-field performance and lifespan of PV modules are affected by the interaction of numerous parameters, among which temperature, strain, and humidity. Among these parameters, only temperature is occasionally measured in PV installations, and such monitoring is often external to the module. This limits its use and does not provide accurate...master thesis 2021

Eipe, Jonathan Joe (author)The Static Recrystallization (SRX) phenomenon of austenite in C-Mn steels have a large impact on the final mechanical properties of the steel. However, the austenite recrystallization kinetics are difficult to investigate experimentally, due to solid-state phase transformations during cooling to room temperature. The best model alloys to examine...master thesis 2021

Roth, Caspar (author)Self-healing ability in polymers is typically probed by monitoring restorative properties after localized macroscopic damage or repetitive cycles of destructive testing followed by a healing cycle (e.g. cut-and-heal tests). However, the restoration of homogeneously distributed damage before ultimate failure remains largely unattended in...master thesis 2021

Seignette, Tijmen (author)Running Specific Prosthesis (RSP) allow amputee sprinters to compare to the best able-bodied sprinters in the world. In RSP research, the current state of the art mainly focusses on highly detailed analysis of discrete moments in the sprint, but more data of the entire sprint process in terms of RSP characteristics and sprinting technique are...master thesis 2021

van Dam, Daniël (author)Suspended microchannel resonators are a kind of mechanical resonator with an embedded microchannel inside. This is done as for some samples it is convenient or even necessary to put the sample into a fluid. The sample can then travel through the channel and its mass can be determined. The channel also simplifies placement of the samples compared...master thesis 2021

Obers, Siemen (author)The aim of this thesis is to determine the influence of the Y/T, yield to tensile strength, ratio on the stress fields of high strength steels. This is relevant to the offshore industry as regulations restrict the use of steels with a high yield to tensile strength ratio, which is a characteristic of high-strength and<br/>ultra high-strength...master thesis 2021

Hofman, Pieter (author)A common choice for multiscale modeling of the mechanical response of composites is to use periodic boundary conditions (BCs) on square representative volume elements (RVEs). However, these periodic BCs over-constrain the response when strain localization takes place in bands that are not compatible with the imposed periodic constraints....master thesis 2021

Voortman, Rick (author)The city of Amsterdam contains about 1600 bridges and 600 kilometres of quay walls. Of these walls, about 200 kilometres are of masonry walls placed on a timber floor and founded on timber piles. These quay walls are sometimes over 100 years old. Due to the increasing loads in the past century and the degrading of material properties in the...master thesis 2021

Tziotziou, Aikaterini (author)Atherosclerosis is a prevalent cardiovascular disease and defined as plaque formation inside the arterial intima layer. The atherosclerotic plaque is characterized as anisotropic, soft tissue and a potential plaque rupture could result in life-threatening clinical events, such as ischemic attack or stroke. The plaque rupture mechanism is still...master thesis 2020
