Cure-induced residual stresses for warpage reduction in thermoset laminates

Struzziero, G. (author), Nardi, D. (author), Sinke, J. (author), Teuwen, Julie J.E. (author)

The paper addresses the role played by the cure stage of a vacuum assisted resin transfer molding process in residual stresses generation. The Airstone 780E epoxy resin and Hardener 785H system broadly used in the wind turbine blade industry has been used in this study. The viscous–elastic properties of the resin have been characterized and...

Modelling of membrane bonding response: Part 1 development of an adhesive contact interface element

Liu, X. (author), Kasbergen, C. (author), Li, J (author), Scarpas, Athanasios (author)

The adhesive bonding strength of the membrane layers between the asphalt concrete surface layers and the decks of steel bridges has a strong influence on the fatigue life of orthotropic steel deck bridges (OSDBs). The most important requirement for the application of membrane materials to orthotropic steel deck bridges is that the membrane...

Modelling of membrane bonding response: Part 2 finite element simulations of membrane adhesion tests

Liu, X. (author), Kasbergen, C. (author), Li, J (author), Scarpas, Athanasios (author), Tzimiris, G. (author)

The adhesive bonding strength of the membrane layers between the asphalt concrete surface layers and the decks of steel bridges has a strong influence on the fatigue life of orthotropic steel deck bridges (OSDBs). The interfacial properties between the membrane and the layers bonded to it have not been extensively studied in the current...

Modelling of five-point bending beam test for asphalt surfacing system on orthotropic steel deck bridges

Liu, X. (author), Li, J (author), Tzimiris, G. (author), Scarpas, Athanasios (author)

The orthotropic steel deck bridges (OSDBs) in the Netherlands consists mostly of multilayer system: top porous asphalt layer, guss asphalt layer, steel deck and two membrane layers. The five-point bending (5PB) beam test is the standard device in France for characterization of fatigue response of asphalt concrete surfacings used on...

Thermo-Hydrodynamic Analysis of a Plain Journal Bearing on the Basis of a New Mass Conserving Cavitation Algorithm

Alakhramsing, S. (author), Van Ostayen, R.A.J. (author), Eling, R.P.T. (author)

Accurate prediction of cavitation is an important feature in hydrodynamic bearing modeling. Especially for thermo-hydrodynamic modeling, it is crucial to use a mass-conservative cavitation algorithm. This paper introduces a new mass-conserving Reynolds cavitation algorithm, which provides fast convergence and easy implementation in finite...

Performance and scalability of finite-difference and finite-element wave-propagation modeling on Intel's Xeon Phi

Zhebel, E. (author), Minisini, S. (author), Kononov, A. (author), Mulder, W.A. (author)

With the rapid developments in parallel compute architectures, algorithms for seismic modeling and imaging need to be reconsidered in terms of parallelization. The aim of this paper is to compare scalability of seismic modeling algorithms: finite differences, continuous mass-lumped finite elements and discontinuous Galerkin finite elements. The...

On stabilization of loosened hip stems via cement injection into osteolytic cavities

Andreykiv, A. (author), Janssen, D. (author), Nelissen, R.G.H.H. (author), Vlastar, E.R. (author)

Background Cement injection into osteolytic areas around the cement mantle is a technique for refixation of loose hip implants for patients who cannot undergo standard revision surgery. Preliminary clinical results show the improvement in walking distance, patients' independence and pain relief. Methods In this study, we use a detailed finite...

Design of a deployment rotation mechanism for microsatellite

Abdelal, G.F. (author), Bakr Elhady, A. (author), Kassab, M. (author)

Solar array rotation mechanism provides a hinged joint between the solar panel and satellite body, smooth rotation of the solar array into deployed position and its fixation in this position. After unlocking of solar panel (while in orbit), rotation bracket turns towards ready-to-work position under the action of driving spring. During...
