Yeh, Haoming (author)During the preoperative planning for breast-conserving surgery, the surgeon makes use of an MRI scan of the breast cancer patient in the prone position to accurately locate the tumour. However, surgery is performed with the patient in the supine position. The surgeon needs to mentally translate the location of the tumour from the prone position...master thesis 2023

van Zwieten, G.J. (author)A vital component in the management of seismic hazard is the study of past seismic events. Classically, this has been the domain of seismology, which studies the dynamic manifestations of the event to infer properties such as epicenter and moment magnitude. More recently it has become possible to perform similar analyses on the basis of the...doctoral thesis 2023

Weiler, Marnix (author)During ‘float-out’ installation of export cables, the cable is pulled to shore while floating, supported by inflatable floaters. Understanding the hydrodynamic behaviour of these cable-floater-systems (CFS’s) is important, to be able to relate the hydraulic environment to the cable stresses and determine the maximum allowed hydraulic conditions...master thesis 2023

Liaudat, J. (author), Dieudonné, A.A.M. (author), Vardon, P.J. (author)Geological Disposal Facilities (GDF) for radioactive waste will generally rely on clay-rich materials as a host geological formation and/or engineered barrier. Gas will be produced within the GDF, which can build up significant gas pressure and will activate the migration of gas through the clay materials via different transport mechanisms....journal article 2023

Allahyari, P. (author), Silani, M. (author), Yaghoubi Nasrabadi, V. (author), Milovanovic, P. (author), Schmidt, F. N. (author), Busse, B. (author), Qwamizadeh, M. (author)Bone encompasses a complex arrangement of materials at different length scales, which endows it with a range of mechanical, chemical, and biological capabilities. Changes in the microstructure and characteristics of the material, as well as the accumulation of microcracks, affect the bone fracture properties. In this study, two-dimensional...journal article 2023

Xin, Haohui (author), Liu, Jielin (author), Correia, J.A.F.O. (author), Berto, Filippo (author), Veljkovic, M. (author), Qian, Guian (author)In this paper, a numerical simulation method of mixed-mode fatigue crack propagation was explored using the extended finite element method (XFEM) and the Virtual Crack Closure Technique (VCCT). Both 2D and 3D numerical models were selected to simulate the fatigue crack propagation of steel specimens. Two coefficients were proposed to...journal article 2023

Firouzi, A. (author), Yazdani, S. (author), Tavangar, R. (author), Shakerifard, B. (author), Khan MD, F. (author)In the present study, the fracture toughness of hardened and tempered powder metallurgical (PM) high-speed steel ASP 2030 was investigated using notched and unnotched bending specimens and the finite element method. The normal flexural strength of notched and unnotched specimens marquenched by austenitizing at 1150, 1170, and 1185°C, followed...journal article 2023

Singh, Diwakar (author), Sharma, S. (author), Kumar, Rajeev (author), Chauhan, Vishal S. (author), Vaish, Rahul (author)Although conventional actuators like piezoelectric and electrostrictive are efficient, but they required hard wiring, which contaminates the control signal and adds to the weight of the structure. The current study presents a wireless control strategy using photostrictive actuators. Owing to the fortunate combination of photovoltaic effect...journal article 2023

Xu, F. (author), Hajibeygi, H. (author), Sluys, Lambertus J. (author)In fractured geological formations, as a result of the in-situ stress changes, fractures can propagate or slide. This phenomenon can be efficiently modeled by the extended finite element method (XFEM) when there are only a few fractures present. However, geological reservoirs contain many fractures which can also cross and are densely...journal article 2023

Jiménez Rios, Alejandro (author), Plevris, Vagelis (author), Nogal Macho, M. (author)Bridge infrastructure has great economic, social, and cultural value. Nevertheless, many of the infrastructural assets are in poor conservation condition as has been recently evidenced by the collapse of several bridges worldwide. The objective of this systematic review is to collect and synthesize state-of-the-art knowledge and information...review 2023

Nastos Konstantopoulos, C. (author), Komninos, P. (author), Zarouchas, D. (author)A hybrid methodology based on numerical and non-destructive experimental schemes, which is able to predict the structural level strength of composite laminates is proposed on the current work. The main objective is to predict the strength by substituting the up to failure experiments with non-destructive experiments where the investigated...journal article 2023

Xin, Haohui (author), Liu, Jielin (author), Correia, Jose A.F. (author), Berto, Filippo (author), Veljkovic, M. (author), Yang, Fei (author)Strengthening fatigue damage of orthotropic steel decks (OSDs) needs to comprehensively consider the strengthening effect and the dead weight introduced during the strengthening process, especially for OSDs in super large-span bridges or old renovated bridges, where the dead weight cannot be significantly increased during repair and...journal article 2023

Schmidt, Mathias (author), Noel, L.F.P. (author), Doble, Keenan (author), Evans, John A. (author), Maute, Kurt (author)This paper presents an immersed, isogeometric finite element framework to predict the response of multi-material, multi-physics problems with complex geometries using locally refined discretizations. To circumvent the need to generate conformal meshes, this work uses an extended finite element method (XFEM) to discretize the governing...journal article 2023

Sharma, S. (author), Longo, M. (author), Messali, F. (author)Historical quay walls constructed in unreinforced masonry are integral elements of many cities. Originally designed as gravity retaining walls, they are nowadays often subjected to the action of traffic loads as a result of vehicles travelling on roads constructed on their backfill. This paper presents a numerical analysis procedure for carrying...journal article 2023

Brar, Arshdeep Singh (author)The problem of modelling plasticity in materials has been investigated for the past 200 years. Standard theories on yielding for metals go back to the era of Tresca(1864) and von Mises(1913). The rapid rise of the finite element method and new testing techniques in the last few decades led to further research. This thesis aims to model large...master thesis 2022

de Roos, Simone (author)One-third of the Dutch dike system consists of peat dikes. Drought causes these dikes to crack and fail more easily. Visual dike inspections are therefore inefficient, especially considering the increasing climate changes of the future. Research has shown that a fiber optic sensor cable (FOS), used in distributed temperature sensing (DTS), can...master thesis 2022

van Krimpen, Eline (author)Treatment of early stage breast cancer is generally invasive to a patient's daily life while being treated. Therefore, to diminish the physical and psychological impact during and after recovery, a newly proposed minimally invasive therapy for early-stage breast cancer treatment is proposed. Within this study, this proposed treatment is modelled...master thesis 2022
