Jankovic, D. (author), Van Mier, J.G.M. (author)Drying of porous media, such as cement paste, is observed through different types of experiments at meso- and micro-scales. Important aspect is the transport of water through the porous material. The results from Nuclear Magnetic Resonance (NMR) drying experiments have been numerically modeled by means of Lattice Gas Automaton (LGA) from...conference paper 2003

Ten Cate, A. (author), Nieuwstad, C.H. (author), Derksen, J.J. (author), Van den Akker, H.E.A. (author)A comparison is made between experiments and simulations on a single sphere settling in silicon oil in a box. Cross-correlation particle imaging velocimetry measurements were carried out at particle Reynolds numbers ranging from 1.5 to 31.9. The particle Stokes number varied from 0.2 to 4 and at bottom impact no rebound was observed. Detailed...journal article 2002

Kalikmanov, V.I. (author), De Leeuw, S.W. (author)We propose a self-consistent mean-field lattice-gas theory of intercalation compounds based on effective interactions between interstitials in the presence of the host atoms. In addition to short-range screened Coulomb repulsions, usually discussed in the lattice gas models, the present theory takes into account long-range effective attractions...journal article 2002

Jankovic, D. (author), Küntz, M. (author), Van Mier, J.G.M. (author)Modelling of fluid-flow and the resulting effects on shrinkage and microcracking by means of a combination of two lattice models are presented. For the moisture transport, a Lattice Gas Automaton (LGA) is adopted since it can effectively model moisture loss, whereas for cracking simulation a Lattice Fracture Model (LFM) is used. The resultant...conference paper 2001

Jankovic, D. (author), Van Mier, J.G.M. (author)The goal of this study is to develop a numerical model for the simulation of crack growth due to moisture flow in the porous zone between aggregate and matrix (interfacial transition zone, ITZ), where cracking in concrete originates. Two models are coupled based on similarities in their mesh shape: a Lattice Gas Automaton for moisture flow and a...journal article 2001

Suiker, A.S.J. (author), Metrikine, A.V. (author), De Borst, R. (author)This paper discusses the steady state response of a rigidly supported, granular layer to a moving load. Accordingly, the dynamic behaviour of a ballast layer under an instantaneous train axle passage is simulated, where the rigid support reflects a substratum that is much stiffer than the ballast layer, e.g. ballast in a concrete railway tunnel...journal article 2000

Sadouki, H. (author), Van Mier, J.G.M. (author)In this paper a numerical model for simulating crack growth processes caused by moisture movement in a porous multiphase material like concrete is proposed. In the model, the material is schematized as a regular triangular network of beam elements. The meso-material structure of the material is projected on top of the lattice and different...journal article 1996

Romeijn, A. (author)Circular hollow sections are frequently used in structures subjected to fatigue loading such as bridges, offshore structures and cranes. These sections are generally connected by direct welding of the sections to each other. For the design of these welded connections, information is required on the fatigue behaviour. Especially for multiplanar...journal article 1994

van Leeuwen, H.P. (author)The concept of fugacity is explained. Application of compressibility and fugacity data in hydrogen embrittlement calculations is discussed. Equations of state are reviewed. Compressibility factors and fugacity coefficients are calculated. A best estimate is proposed.report 1983

TEM "in situ" straining and bulk studies of the selection of glide systems in f.c.c. single crystalsKo1kman, H.J. (author)Plastic deformation of f.c.c. single crystals was studied by means of straining experiments inside a transmission electron microscope on Cu foils and some related bulk straining experiments on Cu and Al single crystals. In the foils and bulk crystals with the same orientation of the normal to the large face the same non-primary glide...report 1980
