Ruan, J. (author), Ghose, R. (author), Mulder, W.A. (author)Modelling dynamic rupture is essential to correctly describe the process of induced seismicity. Defmod, an open-source finite-element code featuring quasi-static loading, co-seismic volumetric strain, and dynamic rupture, is used to simulate the entire chain of induced seismicity, from pressure evolution due to fluid injection and extraction,...abstract 2020

van Kan, J.J.I.M. (author), Segal, A. (author), Vermolen, Fred (author)Partial differential equations are paramount in mathematical modelling with applications in engineering and science. The book starts with a crash course on partial differential equations in order to familiarize the reader with fundamental properties such as existence, uniqueness and possibly existing maximum principles. The main topic of the...book 2023

Shang, Y. (author), Nogal Macho, M. (author), Wolfert, A.R.M. (author)A co-simulation solution based on direct equilibrium of contact forces is proposed to simulate vehicle-track interaction (VTI) dynamics. It is developed in two platforms, which presents an iterative feedback loop that exchanges contact force files and structure response field in real-time. The load vector acting on the structure is described by...book chapter 2022

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

Coenders, J.L. (author)This paper presents two novel open source software developments for design and engineering in the built environment. The first development, called “sustainability-open” [1], aims on providing open source design, analysis and assessment software source code for (environmental) performance of buildings, structures and infrastructure. The aim of...conference paper 2013

Deng, X. (author), Naeimi, M. (author), Li, Z. (author), Qian, Z. (author)A modeling procedure to predict the residual fatigue life of rail at squats seeds is developed in this article. Two models are involved: a 3D explicit Finite Element (FE) model to compute the stress and strain at squats in rail, and the J-S fatigue damage model to determine the residual fatigue life on the basis of the computed stress and strain...conference paper 2014

Caggiano, A. (author), Pepe, M. (author), Koenders, E.A.B. (author), Martinelli, E. (author), Etse, G.J. (author)Heat production induced by the hydration reaction and the resulting temperature evolution in the early phases of setting and hardening processes are critical phenomena, often leading to premature cracking of concrete members. However, the interest for simulating such phenomena is also related to the fundamental relationships between the nature...conference paper 2012

Tapeinos, I. (author), Koussios, S. (author), Groves, R.M. (author)This paper outlines the structural performance of a conformable pressurizable tank consisting of intersecting spherical shells (multi-cell tank). Multi-cell tanks outrival conventional multiple cylindrical tanks in volumetric efficiency when required to fit in a rectangular envelope in the automotive industry. When pressurized, the multi-cell ...conference paper 2015

(author)The coupled mechanical–thermal behaviour of wheel and rail materials under rolling contact is studied to determine the temperature rise due to the frictional heat. The wheel–rail frictional rolling contact problem is solved using the three–dimensional finite element (FE) method. The FE model considers the wheel tread–rail top contact with...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

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

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
