He, C. (author), Yang, Z. (author), Zhang, P. (author), Li, S. (author), Naeimi, M. (author), Dollevoet, R.P.B.J. (author), Li, Z. (author)Polygonal wear is a type of damage commonly observed on the railway wheel tread. It induces wheel-rail impacts and consequent train/track components failure. This study presents a finite element (FE) thermomechanical wheel-rail contact model, which is able to cope with the three possible generation and development mechanisms of polygonal wear...journal article 2024

Jain, A. (author), Metrikine, A. (author), Steenbergen, M.J.M.M. (author), van Dalen, K.N. (author)Railway transition zones (RTZs) experience higher rates of degradation compared to open tracks, which leads to increased maintenance costs and reduced availability. Despite existing literature on railway track assessment and maintenance, effective design solutions for RTZs are still limited. Therefore, a robust design criterion is required to...journal article 2024

van Tunen, Rick (author)Congenital heart disease (CHD) affects almost 1% of newborns. Right ventricular outflow tract (RVOT) CHD affects 20% of newborns and includes anomalies such as tetralogy of Fallot (TOF) with or without pulmonary atresia, transposition of the great vessels, and truncus arteriosus. All these anomalies require RVOT reconstruction. Prosthetic heart...master thesis 2023

Kluwer, Thomas (author)Global warming has caused an increasing demand for renewable energy. Currently, 50% of the renewable energy is provided by wind and solar combined. However, these renewable energy sources are highly volatile. Wave energy converters can provide a stable renewable energy source. Previous research has contributed to understanding various combined...master thesis 2023

Van Steen, C. (author), Van Beirendonck, T. (author), Vrijdaghs, R. (author), Hendriks, M.A.N. (author), Verstrynge, E. (author)Bond deterioration is one of the major consequences of reinforcement corrosion in reinforced concrete (RC) structures. In this paper, a two-phased numerical modelling approach is presented that aims to determine the constitutive behaviour (bond–slip) at the reinforcement-concrete interface at a certain corrosion level. The novelty of the...journal article 2023

Huang, Y. (author), Gu, D. (author), Mustafa, S. (author), Grunewald, S. (author), Lukovic, M. (author)Ultra-high performance fiber reinforced concrete (UHPFRC) is an advanced cementitious composite with high compressive strength and low permeability. Due to its excellent mechanical properties and superior durability, UHPFRC is considered promising for strengthening of the existing concrete bridges. In order to examine its strengthening...journal article 2023

Wang, L. (author), Wang, Ping (author), Wei, Kai (author), Dollevoet, R.P.B.J. (author), Li, Z. (author)To investigate the train-induced ground vibration, an explicit time-domain, three dimensional (3D) finite element (FE) model is developed. The train, track, embankment, pile-board structure and nearby ground soils are all fully coupled in this model. The complex geometries involving the track components and pile-board structure are all...journal article 2022

Yousefi, Armin (author), Serjouei, Ahmad (author), Hedayati, R. (author), Bodaghi, Mahdi (author)In the present study, the fatigue behavior and tensile strength of A6061-T4 aluminum al-loy, joined by friction stir spot welding (FSSW), are numerically investigated. The 3D finite element model (FEM) is used to analyze the FSSW joint by means of Abaqus software. The tensile strength is determined for FSSW joints with both a probe hole and a...journal article 2021

Wang, H. (author), Liu, X. (author), Zhang, H. (author), Apostolidis, P. (author), Erkens, S. (author), Scarpas, Athanasios (author)Crumb rubber modified bitumen (CRMB) can be considered as a binary composite system where rubber particles are embedded in the bitumen matrix. The bitumen-rubber interaction process (mainly swelling) significantly changes the mechanical properties of both bitumen and rubber phases. This study aims to predict the complex moduli of CRMB binders...journal article 2020

Gupta, D.K. (author), Barink, Marco (author), Langelaar, Matthijs (author)Concentrated photovoltaics (CPV) has recently gained popularity due to its ability to deliver significantly more power at relatively lower absorber material costs. In CPVs, lenses and mirrors are used to concentrate illumination over a small solar cell, thereby increasing the incident light by several folds. This leads to non-uniform...journal article 2018

Lonsain, J. (author)Aeroelastic analyses traditionally consider the airfoil of a wing to remain rigid, only allowing deformation in the span-wise direction of the wing. Recent investigations have shown the benefits of adding chord-wise flexibility in the trailing edge of a wing, however so far only two-dimensional studies have been carried out. Therefore, the...master thesis 2017
