(author), Mirzaali, Mohammad J. (author), Apachitei, I. (author), Fratila-Apachitei, E.L. (author), Zadpoor, A.A. (author)The currently available treatments for inner ear disorders often involve systemic drug administration, leading to suboptimal drug concentrations and side effects. Cochlear implants offer a potential solution by providing localized and sustained drug delivery to the cochlea. While the mechanical characterization of both the implants and their...journal article 2024

Inamdar, A.S. (author), van Soestbergen, Michiel (author), Mavinkurve, Amar (author), van Driel, W.D. (author), Zhang, Kouchi (author)Moulding compounds used for encapsulating electronics typically occupy a large portion of package volume and are most exposed to the external environment. Under harsh conditions such as high temperature, humidity, and mechanical vibrations, constituent materials of electronic components degrade, resulting in a change in their thermal, mechanical...conference paper 2023

Jain, A. (author), van Dalen, K.N. (author), Metrikine, A. (author), Faragau, Andrei B. (author), Steenbergen, M.J.M.M. (author)ransition zones in railway tracks experience strong amplification of stress and strain fields due to the passage of train over inhomogeneity. The inhomogeneity in these zones can be attributed to changes in mechanical properties of material along the longitudinal direction of the track, and to displacement/traction discontinuities at interfaces...conference paper 2023

(author), Xu, Xiao Yun (author)Introduction: Thoracic endovascular aortic repair (TEVAR) of the arch is challenging given its complex geometry and the involvement of supra-aortic arteries. Different branched endografts have been designed for use in this region, but their haemodynamic performance and the risk for post-intervention complications are not yet clear. This study...journal article 2023

Valiya Valappil, S. (author), Goosen, J.F.L. (author), Aragon, A.M. (author)Ultrasonic flowmeters that use transit-time ultrasonic transducers face measurement errors due to 'crosstalk,' whereby the working signal travels through the pipe wall and couplings, interfering with the signal from the fluid. Although various procedures have been proposed to solve the issue of crosstalk, they're limited to low-frequency...journal article 2023

Khosroshahi, Siamak Farajzadeh (author), Masina, M. (author), Antonini, A. (author), Ransley, Edward (author), Brownjohn, James Mark William (author), Dobson, Peter (author), D’Ayala, Dina (author)Maintaining offshore steel structures is challenging and not environmentally friendly due to the frequent visits for inspection and repairs. Some offshore lighthouses are equipped with carbon steel helidecks fixed onto their lantern galleries in the 1970s to provide easy and safe access to maintenance staff and inspectors. Even though the...journal article 2022

Cui, Z. (author), Fan, X. (author), Zhang, Kouchi (author)In this paper, a 3D and fully coupled electromigration modeling is implemented using COMSOL. The fully coupled multi-physics theory has a unique set of partial differential equations, which cannot be directly simulated with the standard finite element software such as ABAQUS and ANSYS. With the weak form PDE modulus in COMSOL, the weak form of...conference paper 2022

Ghavamian, F. (author)We study the acceleration of the finite element method (FEM) simulations using machine learning (ML) models. Specifically, we replace computationally expensive (parts of) FEM models with efficient ML surrogates. We develop three methods to speed up FEM simulations. The primary difference between these models is their degree of intrusion into the...doctoral thesis 2021

Moreira Arouche, M. (author), Teixeira De Freitas, S. (author), de Barros, Silvio (author)The goal of this paper is to evaluate the strain-based partitioning method (SBM), an analytical method based on beam analysis, for the mixed-mode fracture characterization of asymmetric cracks. The fracture energy is calculated at the crack tip of mixed-mode bending (MMB) test with asymmetric geometry and asymmetric material parameters. The...journal article 2021

Sime, Nathan (author), Maljaars, J.M. (author), Wilson, Cian R. (author), van Keken, Peter E. (author)Tracer methods are widespread in computational geodynamics for modeling the advection of chemical data. However, they present certain numerical challenges, especially when used over long periods of simulation time. We address two of these in this work: the necessity for mass conservation of chemical composition fields and the need for the...journal article 2021

Grund, Mitchel (author)The city of Amsterdam has a large number of old quay walls with rotten foundation piles. These foundation piles need to be identified and measures need to be taken. The urban quay walls are supported by two types of foundation: pinewood piles, which are easily affected by bacterial decay and spruce piles. To understand the mechanical behaviour...master thesis 2020
