Kamijo, T. (author), de Winter, S. (author), Panditha, P. (author), Meulenkamp, E. (author)The transparent conductive electrode (TCE) is a key component of organic light-emitting diodes (OLEDs). High-resolution printed metal grids are a promising alternative to indium tin oxide (ITO). We present results for evaporated OLEDs with a printed copper (Cu) grid with line width below 3 μm. The use of a thick doped hole injection layer (HIL)...article 2022

Xu, Q. (author), Hofmeyer, H. (author), Maljaars, J. (author), van Herpen, R.A.P. (author)This paper presents two full-scale fire resistance tests of sandwich panels with connections, to verify one way coupled fire-structure simulations. The heat transfer simulations agree well with the tests, however, the structural response simulations show some differences compared to the start of the first test, which is a sandwich panel façade....conference paper 2022

Hofmeyer, H. (author), Vervoort, E.M.C. (author), Snijder, H.H. (author), Maljaars, J. (author)An existing theoretical model indicates that the behaviour of trapezoidal steel sheeting under combined web crippling and bending moment may be modelled by only the sheeting's compressed flange. Therefore, this paper presents finite element models that simulate only the compressed flange of the sheeting, applying a prescribed displacement field...conference paper 2018

Gupta, D.K. (author), Barink, M. (author), Langelaar, M. (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...article 2018

Slobbe, A. (author), Allaix, D.L. (author), Courage, W. (author), van Vliet, A.B. (author)The accuracy of predictions of structural behavior by finite element analysis strongly depends on the formulation of the numerical model. Depending on the problem at hand, the analyst has to make a number of choices, which influence the numerical results to a greater or lesser extent. For complex cases, e.g. existing reinforced concrete...conference paper 2017

Vanegas-Acosta, J.C. (author), Lancellotti, V. (author), Zwamborn, A.P.M. (author)Purpose– Electric fields (EFs) are known to influence cell and tissue activity. This influence can be due to thermal or non-thermal effects. While the non-thermal effects are still matter of discussion, thermal effects might be detrimental for cell and tissue viability due to thermal damage, this fact being exploited by applications like...article 2015

Espana, A.L. (author), Nijhof, M.J.J. (author), Williams, K.L. (author), Plotnick, D.S. (author), Marston, P.L. (author)When attempting to detect and classify objects in an ocean environment, it has been shown that the surrounding environment, specifically the target’s deployment within that environment, greatly affects the measured acoustic response. While sea trials go a long ways towards extending the development of better classification systems, they are...conference paper 2014

Bechtold, T. (author), Hohlfeld, D. (author), Rudnyi, E.B. (author), Günther, M. (author)In this paper we present a novel highly efficient approach to determine material properties from measurement results. We apply our method to thermal properties of thin-film multilayers with three different materials, amorphous silicon, silicon nitride and silicon oxide. The individual material properties are identified by solving an optimization...article 2010

Maljaars, J. (author), Soetens, F. (author), TNO Bouw en Ondergrond (author)A test series was carried out and reported in a corresponding paper on slender aluminium alloy sections, loaded in compression at elevated temperature. This paper gives the results of simulations of these tests with a finite element model. For this purpose, a novel constitutive model for fire exposed aluminium alloys is used. The critical...article 2009

(author), TNO Bouw en Ondergrond (author)The improvement of passive fire protection of storage vessels is a key factor to enhance safety among the LPG distribution chain. A thermal and mechanical model based on finite elements simulations was developed to assess the behaviour of full size tanks used for LPG storage and transportation in fire engulfment scenarios. The model was...article 2009
