Welcome to Plasticity Group
Nguyen obtained his PhD degree in geotechnical engineering from Imperial College in 2020, working under the supervision of Professor Catherine O’Sullivan. The title of this work is “Micromechanics of shear wave propagation and non-linear stiffness of granular materials”. Development of advanced numerical procedures using the 3D smoothed particle finite element method to Cam Clay plasticity solutions for geomechanics is central to this group. Various approaches (i.e. elastoplastic analysis, limit analysis, and slip line analysis) are applied to solutions for geotechnical problems, and a particular emphasis is placed on the development of constitutive models for soil using: (a) "hyperplasticity", and (b) "the potential particles".
