Malidi, A. (author), Harlen, O. (author)We present a novel Lagrangian finite element method for simulating suspensions of particles in viscoelastic fluids. We solve the flow in a unit cell containing a small number of particles with doubly periodic boundary conditions on a self-replicating two-dimensional lattice to replicate a suspension on an infinite domain. The method uses a...conference paper 2006

Brinkgreve, R.B.J. (author), Post, M. (author)Displacement-based finite element calculations are primarily used for serviceability limit state (SLS) analysis, but the finite element method also offers possibilities for ultimate limit state (ULS) design in geotechnical engineering. The combined use of SLS and ULS calculations with partial safety factors according to the different design...conference paper 2015

Kurilla, L. (author), Achten, H. (author), Florian, M. (author)In order to support an architects decision to evaluate and choose more efficient structural solutions in the concept design, it is necessary to establish an interactive feedback loop between structural solver and geometry modeller which would allow one to analyse a great number of solutions generated in the scripting design process. Defining a...conference paper 2013

Akbas, B. (author), Huvaj, N. (author)This paper compares the results of different probabilistic approaches and emphasizes the necessity of probabilistic analyses in slope stability studies. To do that, Limit Equilibrium Method (LEM) and Finite Element Method (FEM) are utilized and their outputs are compared in terms of probability of failure (PF), reliability index (RI), factor of...conference paper 2015

Chen, X. (author), Sanchez, T. (author), Conciatori, D. (author), Chaouki, H. (author), Sorelli, L. (author), Selma, B. (author), Chekired, M. (author)This paper presents a new 2D water transport model considering capillary suction to predict the water content evolution in the concrete porosity. The basic formulations of the model are illustrated, and a switching algorithm is introduced to simulated wet-drying effects. Two specific absorption tests are studied to validate this model. The first...conference paper 2021

Ito, S. (author), Okuda, H. (author)Computational fluid analysis requires huge amounts of computational resources. However, for the usual developer, parallelization is difficult as it requires special programming skills. In this study, the HPC Middleware is employed, which supports parallelization and optimizations for easily developing parallel code. The parallel efficiency of...conference paper 2006

Svacek, P. (author), Horacek, J. (author)The paper focus on numerical approximation of the coupled of fluid and structural models in aeroelastic simulations as well as to the coupling of both models. The fluid motion is described by the incompressible Reynolds Averaged Navier-Stokes equations (RANS) and coupled with Spallart-Almaras turbulence model. The numerical solution by finite...conference paper 2006

Su, H.Z. (author), Wen, Z. (author), Yang, M. (author)The elastic-plastic mechanical behaviour is a typical characteristic of rock mass. The load action will bring on the local destruction, large deformation, even whole failure of rock mass with the discontinuous mediums (e.g. joint, crack and fault). It is a coupling process of the continuous deformation and the discontinuous deformation. The...conference paper 2015

Li, Z. (author), Jiang, X. (author), Hopman, J.J. (author)Fatigue is one of the major challenges of offshore rigid pipes. The surface crack is the main manifestation. Fatigue cracks are evolved from surface cracks which are frequently appear in the external surface of rigid pipes. Under fatigue loads, the surface cracks may continue to propagate and finally develop into penetrated cracks, which may...conference paper 2018

Jing, R. (author), van Lent, Diederik (author), Kasbergen, C. (author), Scarpas, Athanasios (author), Liu, X. (author), Erkens, S. (author)When oxygen diffuses in a bituminous film, it also reacts, simultaneously, with the constituents of the bitumen and as such it is gradually depleted. This depletion process masks the characteristics of the actual diffusion process and complicates the determination of the diffusion coefficient needed for computation of oxygen concentration and...conference paper 2017

Van der Meer, F.P. (author)There is no state of the art computational model that is good enough for predictive simulation of the complete failure process in laminates. Already on the single ply level controversy exists. Much work has been done in recent years in the development of continuum models, but these fail to predict the correct failure mechanism in cases where...doctoral thesis 2010

Zhao, J. (author)Rail transportation plays an important role in our everyday life, and there is fast development and modernization in the railway industry to meet the growing demand for swifter, safer and more comfortable trains. At the same time, the security of train operation and the maintenance of rails have to be considered. A lot of research on these...doctoral thesis 2015

Guo, Z. (author)The simulation of rubber-like material behaviour by means of the finite element method has been described in this study. Proper material models for the numerical description of static hyper-elasticity, the ideal Mullins effect and the Mullins effect with permanent deformation were proposed, respectively. The second focus of this study was the...doctoral thesis 2006

Ahmed, A.

Pannachet, T. (author)Accuracy of a finite element solution depends greatly on the spatial discretisation of the problem domain. The more refined/enriched discretisation provides better accuracy but also requires more computational cost. For modelling of quasi-brittle failure, the process zone where failure takes place can be very small, thus it is very cost...doctoral thesis 2006

De Boer, A. (author)Introduction (chapter 1) In analysis software models the infrastructural constructions are often reduced to geometrical linear and surface models (plane stress and shell models). The selection of a model much depends on the speed of the analysis process and the total processing time. The increased computer power has boosted the visualisation of...doctoral thesis 2010
