Ngoc-Son Nguyen Associate Professor, UTR Geomech, GeM Institute, Nantes University

Présentation

My teaching activities are mainly given to students at the civil engineering department of the IUT de Saint Nazaire (Nantes University). I teach several subjects: mechanics of granular materials, geotechnics, structure mechanics, public works. I give also some courses about programming and computational methods to students of engineer, Master and PhD programs.

My research focus on mechanics of granular materials and the solid-fluid interaction in these materials. Here are my main research topics:- Discrete modeling and simulation of granular materials using the discrete element method (DEM)- Modeling of internal erosion in granular soils- Pore space characterization- Modeling of the fluid flow in saturated or unsaturated granular soils using DEM and lattice Boltzmann method (LBM)- Consequences of scalping and scalping/replacement procedures on mechanical properties of coarse-grained soils- Modeling of interactions between solid grains and fluid by coupling the DEM to SPH method (Smoothed Particle Hydrodynamics)
