Research expertise

Played a key role in the formulation and development of powerful new methods for performing numerical stability analysis for geotechnical structures in two and three dimensions. These methods, which are based on finite elements and nonlinear programming, are the first to be able to compute rigorous bounds on the limit load in three dimensions. Moreover, for large two-dimensional problems, they are several orders of magnitude faster than an equivalent linear programming formulation and can be run on a standard desktop PC. Coupled with convenient domain discretization tools and adaptive mesh refinement, the limit analysis procedures can be applied to a wide range of problems in geotechnical engineering, and obviate the need for more approximate techniques such as limit equilibrium. Indeed, they have already been used to study the behaviour of foundations on jointed rock, square and rectangular foundations, stability of layered soil, tunnels, anchors, excavations and pavements under moving loads.

My research interests have been recently extended to the fields of non-structured mesh generation and adaptivity, shakedown analysis, elastoplasticity by optimization, specialised non-linear optimisation methods such as second-order cone and semidefinite programming.

Collaboration

Has played a key role in the formulation and development of new methods for performing lower and upper bound limit analysis in two and three dimensions. These methods, which are based on finite elements and nonlinear programming, are the first to be able to compute rigorous bounds on the limit load in three dimensions. Moreover, for large two-dimensional problems, they are several orders of magnitude faster than equivalent linear programming formulations. Recently the upper bound method has been enhanced to deal with discontinuous velocity fields subject to general flow rule conditions and united with lower bound techniques under the static framework. The newly developed limit analysis procedures are applicable to a wide range of problems in geotechnical engineering, and obviate the need for approximate techniques such as limit equilibrium. Indeed, they have already been used to study the behaviour of foundations on jointed rock, square and rectangular foundations, tunnels, anchors and excavations.

My research interests have recently been extended to the fields of non-structured mesh generation and adaptivity (completed APD, 2002), shakedown analysis, elastoplasticity by optimization (ARC grant 2006), and specialised non-linear optimisation methods such as second-order cone and semidefinite programming.
