Micro-scale investigations of temperature-dependent Microbial-Induced Carbonate Precipitation (MICP) in the temperature range 4-50 °C
Yuze Wang, Yong Wang, Kenichi Soga +2
Microbially-Induced Carbonate Precipitation (MICP) involves a series of bio-geochemical reactions whereby microbes alter the surrounding aqueous environment and induce calcium carb…
Liquefaction-Induced Dam Failure Simulation -- A Case for the Material Point Method
Ezra Y. S. Tjung, Kenichi Soga
Seismic analysis of earthen dams is paramount to evaluate the risk of potential liquefaction and strain softening that can cause flow failure. Even though the current state of the…
A barrier method for frictional contact on embedded interfaces
Yidong Zhao, Jinhyun Choo, Yupeng Jiang +3
We present a barrier method for treating frictional contact on interfaces embedded in finite elements. The barrier treatment has several attractive features, including: (i) it does…
An HPC-Based Hydrothermal Finite Element Simulator for Modeling Underground Response to Community-Scale Geothermal Energy Production
Xiang Sun, Kenichi Soga, Alp Cinar +5
Geothermal heat, as renewable energy, shows great advantage with respect to its environmental impact due to its significantly lower CO2 emissions than conventional fossil fuel. Ope…
Context-specific volume-delay curves by combining crowd-sourced traffic data with Automated Traffic Counters (ATC): a case study for London
Gerard Casey, Bingyu Zhao, Krishna Kumar +1
Traffic congestion across the world has reached chronic levels. Despite many technological disruptions, one of the most fundamental and widely used functions within traffic modelli…
Effects of bacterial density on growth rate and characteristics of microbial-induced CaCO3 precipitates: a particle-scale experimental study
Yuze Wang, Kenichi Soga, Jason T. DeJong +1
Microbial-Induced Carbonate Precipitation (MICP) has been explored for more than a decade as a promising soil improvement technique. However, it is still challenging to predict and…
Enhancing strength of MICP-treated sandy soils: from micro to macro scale
Yuze Wang, Charalampos Konstantinou, Kenichi Soga +3
Microbial-Induced Calcium carbonate (CaCO3) Precipitation (MICP) has been extensively studied for soil improvement in geotechnical engineering. The properties of calcium carbonate…
Modeling irregular boundaries using isoparametric elements in the Material Point Method
Ezra Y. S. Tjung, Shyamini Kularathna, Krishna Kumar +1
The Material Point Method (MPM) is a hybrid Eulerian-Lagrangian approach capable of simulating large deformation problems of history-dependent materials. While the MPM can represen…
Scalable and modular material point method for large-scale simulations
Krishna Kumar, Jeffrey Salmond, Shyamini Kularathna +4
In this paper, we describe a new scalable and modular material point method (MPM) code developed for solving large-scale problems in continuum mechanics. The MPM is a hybrid Euleri…
A microfluidic chip and its use in characterising the particle-scale behaviour of Microbial-Induced Carbonate Precipitation (MICP)
Yuze Wang, Kenichi Soga, Jason T. DeJong +1
Microbial-Induced Carbonate Precipitation (MICP) is an innovative ground improvement technique which can enhance the strength and stiffness of soils, and can also control their hyd…
Mechanics of granular column collapse in fluid at varying slope angles
Krishna Kumar, Jean-Yves Delenne, Kenichi Soga
This paper investigates the effect of initial volume fraction on the runout characteristics of collapse of granular columns on slopes in fluid. Two-dimensional sub-grain scale nume…
