Piezoelectric energy harvesting technology is an alternative source for powering low power electronics. The ability of piezoelectric materials to convert ambient vibrational energy into usable electrical energy is seen as a promising battery-free solution to be used in inhospitable areas to self-power electronics for a longer time with little...

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...

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...

An enhanced methodology is proposed to include both the loading and the resistance of the upper stem (pipeline) in 18" ILT installation. Loading behavior and buckling capacity have been investigated. The upper stem behaves quasi-statically for all HMC projects, this corresponds to the current method of applying maximum found loads statically....

Near free edges of fibre reinforced composite laminates modelled with homogeneous layers, the presence of high gradient interlaminar stresses has been found theoretically. Over a span of nearly 50 years, various methods, including numerical and analytical have been employed for analysis of the high gradient stresses which sometimes exist to an...

A new technique is developed in this thesis, which applies boundary conditions to moving boundaries in the Material Point Method (MPM). While MPM has been proven to be useful in slope stability, foundation and seabed ploughing modelling, the application of boundary conditions is still a challenge,
because the location of the boundary is...

Cells of the most common organisms like plants and animals are filled with polymeric networks that fulfil important functions of the cell. There is however no analytically solvable model that describes diffusion in such a cell. This thesis presents a model for diffusion in polymeric environments, and some predictions about the behaviour of the...

The design-process of an efficient turbo-machinery relies heavily on the accurate simulation of the internal flow. These simulations come with their own set of challenges, among which is the implementation of the boundary conditions. This thesis extends the Non-reflecting boundary conditions, as first proposed by Giles, to non-ideal compressible...

Seismic interferometry by crosscorrelation has found wide application over the last decade. With which, the Green’s function is retrieved between two receiver positions. Because the bulk of the ambient seismic field consists of surface wave energy, most applications in seismology utilize the surface wave part of the Green’s function. The correct...

Consider an estuary which is described by two governing equations for two variables, the water level 'zeta' and the velocity 'u'. Having two governing equations (Saint-Venant, 1871) is sufficient to perform time integration. The problem statement for a finite domain contains two boundary conditions and an initial condition. However, if the...

Compliant mechanisms (CM) are a growing part of many different fields from MEMS to surgical devices. They offer a solution to classical mechanical drawbacks, such as friction, backlash, lubrication and assembly. One particular field of application concentrates on stiffness balance, also known as static balancing(SB), of mechanical systems. This...

After the flood of 1993 and 1995 in the Netherlands, flood risks in Limburg became an important discussion. Each flood defence system along the river Meuse needs to be provided with a safety level with an annual failure probability of 1/250. In the nearby future a new safety philosophy will be introduced, entailing new safety norms and...

The subsurface in the Western part of the Netherlands is generally characterized as a regional aquifer, in which most of the lateral groundwater flow takes place, covered by a semi-permeable layer. The semi-permeable layer is often split into a phreatic layer on top of an aquitard (which has an even lower permeability). The phreatic layer and...

Extreme value theory is commonly applied in ocean engineering to estimate extreme environmental conditions (e.g. wave height and wind speed). Extreme value models generally assume data are identically distributed and homogeneous in time. Because there are often different dominant generating mechanisms in different seasons, the sample...

For many applications in the field of coastal engineering 2D-morphological models are being applied. Due to the large computational effort these models demand it is nearly impossible to include a full wave climate in long-term morphological modeling. This has asked for waveclimate reduction methods in order to reduce the input and consequently...

The thesis presents a parametric design tool for plate structural analysis. The goal of the thesis is to establish a real-time visualized program for structural calculation and to make it parameterized. The tool is based on a visualized drawing program Rhino with Grasshopper plug-in to generate the parametric environment for the plate structural...

The focus is on the numerical flow model TRIWAQ. It is developed as a hydrostatic free-surface flow model, which is currently being used by the KNMI and Rijkswaterstaat for predictions of water levels in the North Sea and Dutch estuaries. TRIWAQ has successfully been extended to the realm of nonhydrostatic modeling, TRIWAQ-NH, this allows the...

Om problemen betreffende ruimtetekort in de Rotterdamse haven het hoofd te bieden wordt onderzocht of een nieuw haventerrein voor de kust kan worden aangelegd, de TweedeMaasvlakte. Dit terrein moet voldoende worden beschermd tegen golven afkomstig uit zee en hoge waterstanden. Om golfbrekers en andere civieltechnische constructies ten behoeve...

The Storm Surge Barrier in the New Waterway was built to protect the city and port of Rotterdam and the area of the lower Rhine against flooding during extreme conditions. This construction, consisting of two gigantic arc shaped barriers, is to be pivoted into the New Waterway and then lowered in case of an impeding emergency. The arc shape...
