A hybrid discrete-continuum approach to model hydro-mechanical behaviour of soil during desiccation
Khoa M. Tran, Ha H. Bui, Giang D. Nguyen
Desiccation cracking in clayey soils occurs when they lose moisture, leading to an increase in their compressibility and hydraulic conductivity and hence significant reduction of s…
Failure Mechanism of True 2D Granular Flows
Cuong T. Nguyen, Ha H. Bui, R. Fukagawa
Most previous experimental investigations of two-dimensional (2D) granular column collapses have been conducted using three-dimensional (3D) granular materials in narrow horizontal…
A Study of the Matter of SPH Application to Saturated Soil Problems
H. Bui, R. Fukagawa, K. Sako
We present an application of SPH to saturated soilproblems. Herein, the standard SPH formulation was improved to model saturated soil. It is shown that the proposed formulation cou…
Seismic Earth Pressure Development in Sheet Pile Retaining Walls: A Numerical Study
P. Rajeev, Ha H. Bui, N. Sivakugan
The design of retaining walls requires the complete knowledge of the earth pressure distribution behind the wall. Due to the complex soil-structure effect, the estimation of earth…
Large deformation and post-failure simulations of segmental retaining walls using mesh-free method (SPH)
H. H. Bui, J. A. Kodikara, R. Pathegama +2
Numerical methods are extremely useful in gaining insights into the behaviour of reinforced soil retaining walls. However, traditional numerical approaches such as limit equilibriu…
Numerical modelling of sandstone uniaxial compression test using a mix-mode cohesive fracture model
Yilin Gui, Ha H. Bui, Jayantha Kodikara
A mix-mode cohesive fracture model considering tension, compression and shear material behaviour is presented, which has wide applications to geotechnical problems. The model consi…
