A macro-element model for multidirectional cyclic lateral loading of monopiles in clay
(Journal article; Peer reviewed, 2018)This paper investigates numerically the impact of multidirectional cyclic loads on the response of a monopile in clay supporting an offshore wind turbine (OWT). The results indicate that multidirectional loading modifies ... -
Analytical prediction of time-dependent behavior for tunneling-induced ground movements and stresses subjected to surcharge loading based on rheological mechanics
(Peer reviewed; Journal article, 2021)Current analytical solutions on the ground movements and stresses induced by shield tunneling in soft soils are generally based on the instantaneous excavation behavior. Furthermore, previous studies seldom took account ... -
A hybrid finite element model for non-isothermal two-phase flow in deformable porous media
(Peer reviewed; Journal article, 2021)This paper presents a numerical method to model the coupled thermo-hydro-mechanical (THM) processes in porous media saturated with two immiscible fluids. The basic equations of the system have been derived based on the ... -
Isogeometric analysis of THM coupled processes in ground freezing
(Journal article; Peer reviewed, 2017)An isogeometric analysis (IGA) based numerical model is presented for simulation of thermo-hydro-mechanically (THM) coupled processes in ground freezing. The momentum, mass and energy conservation equations are derived ... -
Modelling mesh independent failure loads of a soft strain-softening clay using a rate dependent model
(Peer reviewed; Journal article, 2023)If no regularisation method is used during finite element modelling of strain-softening (brittle) materials, results become mesh dependent: manifesting as very thin shear bands whose thickness and orientation depends on ... -
Novel Bayesian framework for calibration of spatially distributed physical-based landslide prediction models
(Peer reviewed; Journal article, 2020)This study presents a novel Bayesian framework for statistical calibration of spatially distributed physical-based landslide prediction models. The calibration process is formulated in a statistical setting with the model ... -
Strain localisation in sensitive clays: can rate dependency provide mesh independent results?
(Peer reviewed; Journal article, 2022)Finite element modelling involving strain-softening materials becomes mesh dependent if not regularised by a mesh independent length scale. The objective of this paper is to investigate whether the inherent strain rate ...
