Korosteleva, Irina (author)Significant part of geotechnical engineering projects involve the problems related to jointed rock<br/>masses. For example, construction of tunnels in rock or stability analysis of the rock slopes. In this<br/>framework, the finite element modelling is often used for problems with complex geometries or<br/>where the analytical solution is...master thesis 2017

Smit, Thijs (author)Origami has become a source of inspiration in engineering for structural design and the creation of mechanical metamaterials. In the often used analytic geometric and energy methods, it is difficult to incorporate deformation of the faces in non-rigid origami. However, deformation of the faces can play a significant role in their mechanical...master thesis 2017

Gökcek, Volkan Erdem (author)The aim of this thesis is to investigate the behavioral differences of walls that have different load transfer mechanisms and identify a simple engi- neering model for a construction joint that connects these two different wall types.<br/>Within the text; First, the problem description is provided among with a simple yet reliable soil modeling...master thesis 2017

van Dongen, Eef (author)Ice flow, forced by gravity is governed by the Full Stokes (FS) equations, which are computationally intensive to solve due to their non-linearity. Therefore, it has been unavoidable to approximate the FS equations when modeling growth and collapse of an ice sheet-shelf system, which requires simulating many thousands of years. However, the most...master thesis 2017

van Dongen, björn (author)Despite great strides made in understanding and modelling Fiber-Reinforced Polymers (FRPs), their full potential is held back by the inability to accurately predict failure. Contrary to past attempts focused on isolated application of stress-strain and fracture mechanics based failure theories, this research builds upon the existing framework by...master thesis 2017

Stoter, Stein (author)In this work the residual-based variational multiscale method is presented in a discontinuous Galerkin framework. This so-called ‘DG-RVMS’ strategy is developed, extensively verified, and tested on a more complex case.<br/><br/>The proposed DG-RVMS paradigm consists of three principle components. First, the perelement weak form is coupled by...master thesis 2017

De Ruiter, T.M.H. (author)Research shows that the fatigue strength of a Very High Strength Steel (VHSS) can be significantly negatively effected by welds in a structure. The fatigue lifetime may be extended after cracking occurs by means of fatigue crack repair. A better insight by means of Finite ElementModelling (FEM) can help in understanding the effects of a repair...master thesis 2017

Maatkamp, T.W.P. (author)A hot topic in the Netherlands is the safety reassessment of dikes. Currently several (river)dikes are being reinforced to withstand a given normative high water level. The environment of those dikes is often characterised by small floodplains and urban areas right next to the dike, wherefore standard geo-technical measures cannot be applied....master thesis 2016

Kessels, P.C.J. (author)The Reynolds-averaged Navier-Stokes equations are numerically solved in a segregated manner, along with the Spalart-Allmaras turbulence model. The Galerkin as well as multiple stabilized finite element formulations are derived for the Spalart-Allmaras turbulence model, and tested for robustness. For a turbulent channel flow and a backward facing...master thesis 2016

van Oostrum, Joep (author)During applied mechanics courses for undergraduates, the words `finite element' will be mentioned if a structural problem is so complex that it cannot be solved analytically or simply because it would require too much time to solve it by hand. The lecturer refers to a software package and explains how to work with it. Unfortunately, during these...bachelor thesis 2016

Pronk, T.N. (author)A recently recognized application of lattice materials is shape morphing technology, where a structure is expected to take a predefined shape in response to a change in environmental (temperature, pressure, etc.) or loading conditions. In a shape morphing structure that uses a 2D lattice material as the basis, one or more struts in the lattice...master thesis 2016

Arbaciauskas, G. (author)In this paper we are concerned with distributed optimal control problems governed by a second-order linear and semi-linear elliptic partial differential equations (PDE), where the control is distributed on the domain ?. The semi-linear elliptic boundary value problem is analysed by proving the existence of a unique solution and optimal control...master thesis 2016

De Visser, J.L. (author)Unsaturated groundwater dynamics play a major role in the nalysis of soil-atmosphere interaction, stability of geotechnical structures, and the impact of climate change aspects on these subjects. The nonlinear behaviour of water retention in the soil has a large impact on the governing equation known as Richards’ equation, and steep boundary...master thesis 2015

Singh, Niels (author)Nonlinear analysis of dynamic problems has become important for modern industrial design applications. The increasing pressure on airlines to decrease fuel costs demands the design of more efficient aircraft. This requires aircraft manufacturing companies to design lighter structural components. The result is the need for more realistic and...master thesis 2015

Rippi, A. (author)Some dike sections in the Netherlands failed to comply with the safety standards and one of the most promising countermeasures is the construction of retaining walls inside the dike. The Dutch design codes for dikes with retaining walls rely on Finite Element Analysis (FEM) in combination with partial safety factors. However, this can lead to...master thesis 2015

Mieremet, M.M.J. (author)In the field of geotechnical engineering, the study of numerous processes such as pile installation requires to model large deformation of soil. Soil is an assembly of solid particles whose pore volume is filled with water or air. Its deformation mainly depends on the highly non-linear stress-strain behaviour of the soil skeleton. In case of the...master thesis 2015

Winde, H.P. (author)In the last decades, induced earthquakes were caused by the extraction of gas in the Dutch province of Groningen. Both magnitude and frequency of these earthquakes are expected to increase in the following years, causing a threat for the flood defence system. To guarantee the safety against flooding, it is required to take the influence of...master thesis 2015
