Dr Ha Bui is currently a Senior Lecturer in Geomechanics of Department of Civil Engineering, Monash University. He received both his Master and PhD degrees in Civil Engineering (Computational Geomechanics) from the School of Science and Engineering Ritsumeikan University, Japan. He then worked as a Research Fellow at the Department of Civil Engineering at Ritsumeikan University. In 2010, he was awarded the prestigious JSPS Fellowship Award from the Japan Society for the Promotion of Science (JSPS) and worked at Ritsumeikan University until December 2011. He joined Monash University as a full-time tenured academic staff (Lecturer) in 2012.

Dr Bui’s research interests are in the areas of computational mechanics and material modelling with particular focus on large deformation and failure of geomaterials. Leading the Monash Computational Geomechanics (MCG) Lab, Dr Bui works on theoretical and computational modelling of geomaterials (e.g. granular materials, rocks and concretes). The objective of his research is to develop robust computational methods and advanced constitutive models to solve future challenges in geotechnical engineering and geomechanics, with reference to related engineering applications. Typical examples of those problems include slope stabilises and slope failures, gravity driven flows (e.g. granular flows, landslides and avalanches), coupled flow deformation in porous medium (e.g. multi-phase flows, internal erosions, hydraulic fracturing), damage and fracture of brittle and quasi-brittle materials (e.g. rock fractures, fatigue in pavements), thermal-hydro-mechanical coupling processes (e.g. expansive soils and desiccation cracking in soils) and soil-structure interactions. Through his research, Dr Bui aims to advance our understanding on underlying processes that govern the macro-behaviour of geomaterials and make use of these understandings to further advance our current predictive capabilities with references to real-life engineering applications.

Dr Bui is on the Editorial Board for Computers and Geotechnics (Elsevier), one of the leading journal in Geotechnical areas. He is a frequent reviewer for over 20 top journals in the areas of geotechnical engineering, computational geomechanics and solid mechanics. He has also been frequently invited to assess proposals (ARC Discovery Project, ARC Future Fellow, ARC DERAC and ARC Linkage Project) for Australian Research Council (ARC), Research Grants Council (RGC) of Hong Kong and the Canada Research Chairs Program (CRC P).

Research Projects

Current projects

Internal soil erosion: from grain-scale insights to large-scale predictions (ARC Discovery Project, DP190102779)

This project aims to further the understanding of internal soil erosion across different spatial and temporal scales. Internal soil erosion is the most frequent cause of failures of water retaining structures. An approach combining advanced X-ray techniques with particle based methods will be developed to observe, analyse and link different material properties and external conditions governing the erosion process. This will lead to better criteria for soil erosion and numerical tools for field scale failure analysis and risk assessments. The expected outcomes of this project include enhanced capability to assess the integrity and stability of earth structures and better design criteria against erosion.

Liquefaction of silty soils (ARC Discovery Project, DP170103793)

The project aims to develop a numerical approach to understand liquefaction in silty soils. Liquefaction of silty soils in submarine landslides, mine tailings dam failures and cargo liquefaction in vessels carrying iron/nickel ores can cause property loss and be fatal. This project will bridge the behaviours across the scales and deliver constitutive models that possess grain scale mechanisms for better prediction of liquefaction induced failure at the large scales. The expected outcomes are liquefaction criteria for silty soils with different silt contents and numerical tools to predict the onset of liquefaction and flow of liquefied soils.

Desiccation cracking in soils (ARC Discovery Project, DP160100775)

The project will develop a novel fully coupled thermo-hydro-mechanical-atmospheric model to investigate the impact of climate effects on the mechanism of drying shrinkage and associated cracking in soils. Understanding of soil desiccation cracking at the microscale will form the basis for describing the marcroscale soil behaviour as applicable to field problems. Project outcomes will lead to construction of safer and more resilient infrastructures in geotechnical and geoenvironmental engineering.

 

Fatigue cracking in road pavements (ARC Linkage Project, LP130100884)

Some 95% of 900,000 kms roads in Australia are made of unbound granular materials. Majority of these roads have aged significantly and traffic loads and frequency have increased markedly. Road stabilisation by in-situ recycling of old pavement materials using cementitious additives is commonly used as an option with lower environment footprint. The main failure mode of stabilised pavements is by fatigue cracking. Unfortunately, current design methods against fatigue cracking are unsatisfactory and do not take into account key operational factors. This project intends to undertake a bottom-up scientific study to significantly advance the design methods and associated testing of these pavements potentially leading to large cost savings.

Multi-scale modelling of strain localisation in geomaterials with application to slope failures & landslides

Slope failures and landslides cause significant damage to infrastructure and loss of life around the word each year. To protect people and infrastructure against such effects it is important to have proper numerical tools that are capable of predicting such events before they happen. However, modelling such events is very challenging because the slope failures and landslides involve the transitions between solid-like and fluid-like states, phase interaction modelling, appropriate boundary constraints and constitutive modelling; all within the context of motions with complexities on many scales. Furthermore, existing numerical methods are not capable of predicting the large deformation and flow failure behaviour of geomaterials. The purpose of this research is to develop a robust numerical modelling approach capable of accommodating these phenomena with the primary initial goal of predicting possibility of landslide due to heavy rainfall. The basic approach is based on adapting and extending the Smoothed Particle Hydrodynamics (SPH), which is well-suited to modelling large deformation, flow-like phenomena

Computational failure modelling of geomaterials with SPH

The project aims to advance the smoothed particle hydrodynamics (SPH) for large deformation and failure predictions of geomaterials. The SPH was originally invented for astronomic applications by Lucy (1977) and Gingold & Monaghan (1977). Since its invention, SPH has been widely applied to the vast ranges of problems in engineering practices such as: quasi-incompressible fluid flow (Monaghan, 1994), viscous fluid flow (Takeda, 1994; Morris 1997), high velocity impact of solid (Libersky 1993), geophysical flows (Gutfraind and Savage, 1998; Oger and Savage, 1999), etc.

The first SPH application for solving elasto-plastic computation of geomaterials was developed by Bui et al., (2007-2008) where the generic SPH framework for incorporation of existing continuum constitutive models to describe the behaviour of geomaterials was presented. This framework is currently being extended to the wide ranges of applications in computational geomechanics such problems as granular flows, bearing capacity, slope stability analysis and slope failure, landslides and debris flow, soil-structure interaction, coupled flows through deformable porous media, soil-cracking, rock fractures and hydraulic fracturing… etc.

Continuum-discrete modelling of damage and fracture in engineering materials

This project aims to develop an advanced computational approach that combines discrete modelling and enriched contact models based on the plasticity/damage mechanics to simulate damage and fracture in brittle and quasi-brittle materials. In this approach, the Discrete Element Method (DEM), a well-known computational method for simulating large deformation and cracking issues, is utilised as a numerical platform to facilitate the implementation of advanced cohesive contact models based on plasticity-damage mechanics. The nature of discrete modelling is analogous to the internal structure of cemented materials, making it more efficient compared with conventional continuum methods to characterise the failure behaviour of cemented materials. This combined cohesive-discrete modelling approach is  a unique way to perform numerical experiments of brittle and quasi-brittle materials under different boundary conditions.

Coupled fluid-solid SPH approach to modelling flow through deformable porous media

This project aims to develop an advanced computational framework based on the mesh-free smoothed particle hydrodynamics (SPH) method to study the coupled behaviour of fluid and solid in a deformable porous medium. The key feature of the proposed numerical framework is that both solid and fluid phases are solved simultaneously in two different Lagrangian discretisations (or two different sets of Lagrangian particles) using their own governing equations that are linked through several laws of physics. The capability of the SPH method to model large deformation of the solid materials enables the framework to account for the permeability change due to the dilatant shear behaviour of the solid phase. This suggests that the proposed two-phase SPH framework is a promising approach for future studies of coupled problems that involve complex water free-surface/seepage flows and large deformation of soils which are difficult to be modelled using traditional FEM-based coupled two-phase flow models.
