Loutas, T. (author), Eleftheroglou, N. (author)The procedure of damage accumulation in composite materials, especially during fatigue loading, is a complex phenomenon which depends on a number of parameters such as ply orientation, material properties, geometrical non-linearities etc. Towards condition based health monitoring and decision making, the need not only for diagnostic but also for...abstract 2016

Naeimi, M. (author), Li, Z. (author), Petrov, R.H. (author), Dollevoet, R.P.B.J. (author), Sietsma, J. (author), Wu, J. (author)The substantial similarity of fatigue mechanism in a new test rig for rolling contact fatigue (RCF) has been investigated. A new reduced-scale test rig is designed to perform controlled RCF tests in wheel-rail materials. The fatigue mechanism of the rig is evaluated in this study using a combined finite element-fatigue prediction approach. The...conference paper 2014

Latifi, M. (author), Van der Meer, F.P. (author), Sluys, L.J. (author)This paper presents a new damage model for simulating fatigue-driven delamination in composite laminates. This model is developed based on the Thick Level Set approach (TLS) and provides a favorable link between damage mechanics and fracture mechanics through the non-local evaluation of the energy release rate. Previously, this approach has been...conference paper 2015

Veerman, R.P. (author), Koenders, E.A.B. (author)De-icing salts, used on roads in heavy winters, may enter reinforced concrete (RC) structures via its capillary pore system or via cracks, initiating reinforcement corrosion and reducing its remaining service-life. Vehicles passing real bridges exert a dynamic impact action that might activate a fatigue failure mechanism. In order to generate...conference paper 2014

Woldekidan, M.F. (author), Huurman, M. (author), Pronk, A.C. (author)Linear viscoelastic properties of bituminous binders for short loading times are analyzed using dynamic mechanical analysis methods. Dynamic Shear Rheometer (DSR) test with parallel plate (PP) configuration is widely used for this purpose. Due to the complex stress distribution over the cross-section of the test sample, application of this setup...conference paper 2010

Van der Male, P. (author)Offshore wind turbines are highly exposed to timevarying loads. For support structures, estimation of the fatigue damage during the lifetime of the structure is an essential design aspect. This already applies for the preliminary design stage. In determining the dynamic amplification in the frequency domain, modal analysis is a common tool. This...conference paper 2013

Plat-Robain, M. (author)Hypnosis has already been used in very long flights by Bertrand Piccard, one of the two Solar Impulse pilots, to manage fatigue and rest periods. It is also used by navigators like Armel Le Cléac’h during solo races. For this reason we consider it is worth to look at such technics to cope with the constraints of long flights. A study was done in...conference paper 2019

Davila, CG (author), Bisagni, C. (author)The fatigue life of composite stiffened panels with indentation damage was investigated experimentally using single stringer compression specimens. Indentation damage was induced on one of the two flanges of the stringer. The experiments were conducted using advanced instrumentation, including digital image correlation, passive thermography, and...conference paper 2016

Eleftheroglou, N. (author), Zarouchas, D. (author), Loutas, T. (author)This study focused on the in-situ fatigue damage assessment of open-hole carbon/epoxy coupons using Acoustic Emission (AE) and Digital Image Correlation (DIC) techniques. Constant amplitude fatigue tests were performed and the main objective was to investigate the damage process, the degradation process of the fatigue modules and to identify...conference paper 2016

Maarleveld, Arvid (author), Malschaert, D.H. (author), Veljkovic, M. (author)Orthotropic bridge decks are susceptible to fatigue cracks which are influenced by the thickness of their components, welding procedure, type of the weld, the position of the considered detail in relation to the local loading condition and by residual stresses due to welding. The above-mentioned parameters determine the detail category for...conference paper 2022

Den Besten, J.H. (author)Crew transfers, surveillance duties and {security, rescue, interception} operations at sea typically require high-speed craft. Aluminium is quite often selected as hull structure material because of its weight save potential in comparison to steel. The fatigue strength, however, may become a point of concern because of the decreased Young’s...doctoral thesis 2015

van der Tempel, J. (author)To meet growing energy demands, the Kyoto protocol and the much desired diversification of supply, wind energy has become a mainstream source of energy in the EU. Cost wise it is already competing with gas fired electricity. In the last decade wind moved offshore to accommodate even more wind power. The offshore wind resource is more abundant...doctoral thesis 2006

Chougrani, K. (author)Detection and sizing of closed cracks is challenging as these cracks exhibt a transparent behavior when interacting with ultrasonic waves. To face this challenge, high amplitude ultrasonic waves are used by which harmonics are generated at the crack interface. Exploting this non-linear response, the probability of detection and sizing of such...doctoral thesis 2014
