Applications for thermoelastic metamaterials, in which extremely positive, zero or negative thermal expansion is desired, are plentiful. Nevertheless they are rarely applied, due to their poor manufacturability. To enhance their applicability, a topology optimization framework is proposed and verified, able to generate finite thermoelastic...

Power electronic systems are reaching higher efficiencies as their technology advances, which often results in components of smaller size with higher power densities. Cooling these components becomes increasingly challenging as high power densities require cooling with large heat fluxes. Topology optimization (TO) of thermo-fluids can be used to...

In recent developments in the field of multi-material additive manufacturing, differences in material properties are exploited to create printed shape memory structures, which are referred to as 4D-printed structures. New printing techniques allow for the introduction of prestresses in the specimen during manufacturing. This research focuses on...

Although the field of structural optimization has undergone substantial growth the last decades, the efficiency of the programs used to generate structurally optimal designs for industrial applications remains questionable. To make matters worse, as structural problems become more complex, e.g. by adding multi-disciplinary optimization targets...

Shock mounts are crucial components in reducing the transmissibility of a shock or impact, thereby protecting the objective system. Such shock mounts are application-specific and need a redesign for specific uses. This study establishes a transient nonlinear finite element optimization procedure to design a shock mount for withstanding an...

This thesis addresses the capabilities and challenges of automated design approaches, specifically for ap-plication in which a combination of heat transfer and flow is needed. The objective is to use automateddesign approaches from literature and to identify the bottlenecks.For this purpose, an industrial thermal-fluid airshower is designed,...

Building with earthy materials requires new methods to generate architectural geometry and possibly buildings. Topology optimization is a process often used in mechanical engineering and minimizes the volume while still keeping the maximum stiffness. This research implements this process into architectural models, in order to find geometry based...

When considering techniques for producing the Pareto front of a <i>Multi-Objective Optimization Problem</i> (MOOP), there exists a trade-off between the effectiveness of the method in obtaining the Pareto front and the computational cost required to achieve that. For a method to be effective, the generated solutions must result in a true...

In modern ASML machines optical components play an important role in the lithography process. EUV light is transported from the source to wafer by reflective optics. These mirrors are subjected to large thermal loading, as a large portion of the reflected light is absorbed in the mirror structure. The portion of the absorbed light is strongly...

A neutrino is a intriguing subatomic particle. Although the neutrino is the second most abundant known particle in the universe and billions of neutrinos pass through our own body each second, it is not easy to detect them and they remain poorly understood. The detection of neutrinos can help us understand various events happening in space and...

High performance machines such as those used in the semiconductor industry, robotics or racing engines have lots of fast moving parts. The dynamic properties of these moving parts are crucial to the performance of the machine. Therefore these moving parts have to be carefully designed which is often a very time consuming iterative process. In...

This work introduces a new method to deal with design dependent pressure loads in Topology Optimisation (TO) using the SIMP material model. A pronounced focus is on optimising pressure actuated compliant mechanisms. The difficulty herein is the interpretation of the pressure boundary in a TO design. In TO the boundaries are blurry, because of...

The stringent and conflicting requirements of optomechanical instruments and the ever-increasing need for higher resolution and quality imagery demands a tightly integrated design approach. The aim of this study is to drive the thermomechanical design of multiple components of an optomechanical instruments by the system’s optical performance....

Topology optimization is a strong approach for generating optimal designs which cannot be obtained using conventional optimization methods. Improving structural characteristics by changing the internal topology of a design domain has been fascinating scientists and engineers for years. Topology optimization can be described as a distribution of...

Over the years, the installed capacity of offshore wind turbines is increasing rapidly. However, the Levelized Costs Of Energy (LCOE) is still higher than the LCOE of traditional energy production methods like nuclear power or energy from coals or gas. This research focuses on a further decrease of the LCOE, by minimizing the mass of a monopile...

Currently the production process of acoustic guitar factories does not result in instruments with equal dynamical behaviour, due to the varying material properties of wood from tree to tree. Experienced individual guitar builders are able to handle those material variations, but this is a labour intensive process because there is no structured...

Optical systems in high precision equipment become increasingly more complex due to the raising number of optical mounts used for mounting and positioning of optical components. Additional, the installation of electronics and inert gas purging systems to protect the optics against the abrasive optical beam extends the amount of components in the...

Since its introduction, Topology Optimization (TO) has been applied to a broad range of design cases. TO is a material distribution method which finds the optimal material lay-out for a given design space while upholding given constraints and boundary conditions. This has made the method popular in structural mechanics where it is used to find...

In this thesis, a stress recovery procedure for 3-D linear finite elements is presented. The formulation is based on a modified version of the Hu-Washizu variational principle, in which the recovered stresses are calculated by minimizing the error with respect to the directly-computed stresses, and ensuring that the recovered stresses satisfy...
