Associate Professor Yannick Sieffert
Associate Professor Yannick Sieffert research focuses on modelling of the processes of deformation in geomaterial when the constitutive eqnarrays involving softening, namely the localization. More specially, he develops the second gradient model for study the localization problems in the finite element code Lagamine with the coupling effect of thermo-hydo-mechanical. He study also the aspects of loss uniquiness of the numerical solution for a initial boundary-value problem. Yannick received his Ph.D. degree in Civil Engineering from INSA of Lyon (in France) for his dissertation on
Effects of the diaphragm at midspan on static and dynamic behaviour of composite railway bridge in 2004. Since he joined the laboratory 3SR in Grenoble University (in France) as an Associate Professor.
Associate Professor Yannick Sieffert is collaborating with Senior Lecturer Olivier Buzzi to study the localization in unsaturated geomaterials and will be based at the University of Newcastle until December 2012.

Associate Professor Mario Vicente Da Silva
Associate Professor Mario Vicente Da Sliva's research focuses on computational mechanics, namely computational plasticity - numerical implementation of the limit analysis theorems, the use of parallel processing for large scale computations, development of hybrid-mixed finite element models using non nodal Lagrange polynomials as approximation functions and the use of continuum damage mechanics to model the physically non-linear behavior of concrete structures. Mario received his Ph.D. degree in Civil Engineering from (UNL) University Nova of Lisbon for his dissertation on "Tridimensional numerical implementation of the kinematic theorem of limit analysis" and also holds MSc degree in Structural Engineering from IST - Technical University of Lisbon. He briefly worked as a structural design engineer before joining the Faculty of Sciences and Technology of UNL, first as a Teaching Assistant (2002-2009) and later on as an Assistant Professor.
Associate Professor Vicente Da Silva is collaborating with Associate Professor Kristian Krabbenhoft and Associate Professor Andrei Lyamin on various research projects and will be based at the University of Newcastle until September 2012.
