Finite Element Analysis of an embankment failure using MIT-E3 anisotropic soil model.
1) Numerical Analysis:
After completing her PhD at Imperial College in 1996, Dr Zdravkovic became involved with the development and use of the Imperial College Finite Element Program (ICFEP), a specialist finite element program for geotechnical analysis. New developments include constitutive models for partially saturated soils, kinematic yield surface(s) (or bubble) models for stiff clays, extension of the existing Fourier Series Aided Finite Element Method for analysing tunnel heading problems, dynamic soil behaviour and 3D shell elements. She has co-authored, with Professor David Potts of Imperial College, two books on finite element analysis in geotechnical engineering, published by Thomas Telford.
2) Laboratory studies of soil anisotropy:
Dr Zdravkovic supervises laboratory research into soil anisotropy, using the large Imperial College hollow cylinder apparatus. This is a continuation of her PhD work that involved experimental research into the stress-strain-strength anisotropy of granular soils and she has recently been looking into the behaviour of loose, brittle sediments, as well as natural soft clays (from Bothkennar). The results of this work are used to develop and verify constitutive models that are then used in finite element analysis to investigate the effects of soil anisotropy on the behaviour of boundary value problems. Work to date has investigated the behaviour of shallow foundations, offshore suction caissons and anchors and embankments on soft ground.
