There are several methods to perform fatigue assessment as described by the Eurocode 3 and the International Institute of Welding (IIW). The codes establish the relation between stress ranges and their respective number of cycles until failure of the detail. This method is called S-N curves, however this is based mainly on nominal stresses. A...

In this thesis, a methodology is developed that allows for both reliable and computational efficient robustness analysis of aircraft component distortion. This research applies to dis- tortion caused by reductive manufacturing processes that are used to obtain monolithic components from pre-stressed stock material. With the developed methodology...

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...

This thesis aims to provide a better understanding on the relationship between the mechanical and geometrical properties of shell structures. In search hereof, an attempt is made to describe the thrust surface; a geometrical representation of the in-plane force trajectories through a structure. There exists a well-known relation between the...

The Academic Medical Center (AMC) is one of the largest hospitals in the Netherlands and it is located in the Bijlmer district. The complex was built in 1981 and consists of 64 hectares of land. The complex is surround by a green belt where also the former psychiatric center was located. The AMC can be seen as a stand-alone city, with daily...

Additive manufacturing allows material structuring, supporting the fabrication of multiple-level structures or metamaterials. Through the lens of classical stress reduction, nature’s cellular solid structures feature stress-homogenizing nodal topologies. Avian long bones are an example. Research into the mechanics of open cell cellular solids...

The 26th of November 2018, NASA's InSight mission successfully landed on Mars. InSight has a seismometer on board with as main science goal to determine the current level of seismic activity and the impact rate of meteorites on Mars. To process the incoming data of InSight as fast and efficient as possible, a-priori models of seismicity on Mars...

Monitoring fatigue damage is complex because ships are designed to crack after 20 years, and typically cracks will only occur after a long time. A novel fatigue damage sensor has been invented to indicate damage in corresponding aluminium welded joints. Fatigue damage is accelerated by introducing a stress concentration in the sensor w.r.t. the...

Hydrocarbon or geothermal reservoir often consists of several rock layers from different lithology. The various lithologies have their own number of mechanical properties and the layering effect introduced the term of mechanical contrast, which represents the ratio of rock strength between adjacent layers. Mechanical contrast and confining...

Uprising innovative technologies like blockchain and the Internet of Things are increasingly changing the energy domain. These disruptive technologies are becoming more mainstream as a result of media attention and are supported by large multinationals like Tesla and Google. This combined with the enormous CO2 emissions due to fossil fuels and...

Architecture within the last twenty years has developed in many ways. One such direction was reintroducing the physical world and physical phenomenon back to architectural language and design space. This is especially true as buildings have had to become more and more environmentally sustainable and developable with programs such as LEED, BREEAM...

Residual stress analysis within hybrid structures is the focus of this study. The non linear stresses through the thickness are determined using a semi-destructive method known as Incremental Hole Drilling (IHD). Finite element modeling is used to build a mathematical code simulating GLARE laminates with initial residual stresses applied. The...

Multiscale computational homogenization is an efficient method to upscale the microstructural behavior of micro-heterogeneous materials. In this method, a representative volume element (RVE) is assigned to a macroscale material point and the constitutive law for the macroscopic model at that point is obtained by solving a boundary value problem...

For remote islands with high energy prices in the tropics, Ocean Thermal Energy Conversion (OTEC) can be a reliable energy source to supply a renewable baseload for the energy grid. Also, due to the increasing cooling demand, there is a need for sustainable cooling around the equator. This can be supplied by seawater air-conditioning (SWAC). For...

To investigate the damage tolerance of a flexible tsunami barrier, the intralaminar fracture toughness of a plain weave cloth, consisting of Dyneema© fibers and a plastomer resin, has been investigated.
Fracture toughness tests have been performed on center cracked tensile specimens, with varying sizes and initial crack ratios, under quasi...

Post-traumatic stress disorder (PTSD) is a mental disorder that can develop after having experienced a traumatic event and in which a person experiences trauma-related symptoms or impairments in everyday functioning that last for at least a month and sometimes for life (Friedman, F2015). In order to be diagnosed with PTSD, a person must have...

A growing risk of flooding in coastal areas and the corresponding development of legislation drive continuous development in the field of hydraulic engineering. Failure due to
wave overtopping is not fully understood from a physical point of view. Existing knowledge gaps, processes that are not yet explained by physics or not even discovered...
