Han, Shin-Chan (author), Sauber, Jeanne (author), Broerse, D.B.T. (author), Pollitz, Fred (author), Okal, Emile (author), Jeon, Taehwan (author), Seo, Ki Weon (author), Stanaway, Richard (author)Earthquakes involve mass redistribution within the solid Earth and the ocean, and as a result, perturb the Earth's gravitational field. For most of the shallow (<60 km) earthquakes with M<sub>w</sub> > 8.0, the GRACE satellite gravity measurements suggest considerable volumetric disturbance of rocks. At a spatial scale of hundreds of km...journal article 2024

Macchiarulo, V. (author), Milillo, Pietro (author), Blenkinsopp, Chris E. (author), Reale, Cormac (author), Giardina, Giorgia (author)Worldwide, transport infrastructure is increasingly vulnerable to aging-induced deterioration and climate-related hazards. Often, inspection and maintenance costs far exceed the available resources, and numerous assets lack any rigorous structural evaluation. Space-borne synthetic aperture radar interferometry (InSAR) is a powerful remote...journal article 2022

Jommi, C. (author), Muraro, S. (author), Trivellato, Edoardo (author), Zwanenburg, C. (author)Direct observation of gas in peat layers, generated by slow degradation in anoxic conditions, raised concern in the Netherlands about its potential impact on the geotechnical response of dykes founded on peat. To address this issue, an experimental investigation was initiated, aimed at quantifying the main consequences of the presence of gas...journal article 2019

Zhang, Y. (author), Ye, G. (author)In this paper, a new analytic model for predicting chloride diffusivity in unsaturated cementitious materials is developed based on conductivity theory and Nernst-Einstein equation. The model specifies that chloride diffusivity in unsaturated cementitious materials can be mathematically described as a function of chloride diffusivity in...conference paper 2017

Schipper, H.R. (author), Grunewald, S. (author), Troian, S. (author), Raghunath, P. (author), Schlangen, E. (author), Copuroglu, Oguzhan (author)Expensive CNC (computer numerical controlled)-milled formwork is required for the production of double-curved precast concrete elements for cladding or shell structures. The innovative flexible mould method for economically efficient and sustainable production of such elements, developed at Delft University of Technology, comprises the use of a...conference paper 2017

Liu, Y. (author), Janssen, G.C.A.M. (author)The wear of pipelines, used in slurry transport, results in high costs for maintenance and replacement. The wear mechanism involves abrasion, corrosion, impact, and the interaction among them. In this work, we study the effect of impact on the wear mechanism and wear rate. Results show that when the effect of impact is small, the wear mechanism...journal article 2017

(author)The quantification of low rate active tectonic structures is a major target of geodetic and geological studies to improve the knowledge of seismic hazards. The central Betic Cordillera (southern Spain) is affected by moderately active tectonic structures and seismicity. Part of this seismic activity is produced by several NW-SE normal faults...journal article 2014

Grunewald, S. (author), Schipper, H.R. (author), Raghunath, P. (author)This paper describes how curved precast concrete elements can be manufactured in an open and reusable flexible mould. The proposed method reduces formwork costs of architectural freeform elements in concrete. First, the method is described briefly, then a series of tests are discussed, demonstrating that by measuring the rheological parameters...conference paper 2013

Derakhshani, S.M. (author), Schott, D.L. (author), Lodewijks, G. (author)Dust emissions can have significant effects on the human health, environment and industry equipment. Understanding the dust generation process helps to select a suitable dust preventing approach and also is useful to evaluate the environmental impact of dust emission. To describe these processes, numerical methods such as Computational Fluid...conference paper 2013

Griffiths, D.V. (author), Paiboon, J. (author), Huang, J. (author), Fenton, G.A. (author)The classical problem of a beam on an elastic foundation has long been of practical interest to geotechnical engineers, because it provides a framework for computing deflections not only of foundations, but also of vertically oriented laterally loaded piles. The supporting soil can be modelled as an elastic medium, which can be calibrated to...journal article 2012

(author)Uniaxial straining experiments were performed on a rolled and annealed Si-alloyed TRIP (transformation-induced plasticity) steel sheet in order to assess the role of its microstructure on the mechanical stability of austenite grains with respect to martensitic transformation. The transformation behavior of individual metastable austenite grains...journal article 2012

De Hoop, A.T. (author), Abubakar, A. (author), Habashy, T.M. (author)The contrast-source stress-velocity integral-equation formulation of three-dimensional time-domain elastodynamic scattering problems is discussed. A novel feature of the formulation is a tensor partitioning of the relevant dynamic stress and the contrast source volume density of deformation rate. The partitioning highlights several features...journal article 2009

(author)The simulation of migrated and inverted data is hampered by the high computational cost of generating 3D synthetic data, followed by processes of migration and inversion. For example, simulating the migrated seismic signature of subtle stratigraphic traps demands the expensive exercise of 3D forward modeling, followed by 3D migration of the...journal article 2008

Van der Aa, E.M. (author)One of the major problems during welding of thin plate structures is the occurrence of buckling distortion. This type of distortion is caused by the formation of compressive welding stresses; when these stresses exceed a certain critical stress level, the structure will buckle. Most methods for eliminating the welding induced buckling distortion...doctoral thesis 2007

This technique is particularly useful for the fabrication of nanopores with single-nanometer precision, down to 2 nm. We report a detailed study on the effect of electron-beam irradiation on apertures with various...journal article 2005

Beck, S.M. (author)A new model for bed topography is developed herein which accounts for phase lag and the influence of the width to depth ratio. This model is used to analyze four sets of data: two from laboratory channels and two from natural channels. Good agreement is found between the actual and the predicted bed topography. An iterative, two-dimensional...report 1988
