Research, in the field of solid and structural mechanics, has centred on the development of solution procedures for non-linear problems encountered in science and engineering.
Contributed prominently to the development of computational strategies for plastic deformation problems, both for fundamental material studies and for application to Civil and Mechanical structures and components.
Recently focused on the development of discrete element methods for particulate modelling and the simulation of multi-fracturing phenomena in materials.
This work has extended developments in continuum based finitely deforming solids by including damage/fracture based failure and introducing material separation on a local basis to permit modelling of the degradation of a continuum into a multi-fractured particulate state.
Based upon this methodology, contributions have been made to fundamental understanding in several key application areas including:
Explosive simulations which necessitates coupling of the multi-fracturing solid behaviour with the evolving detonation gas distribution
Deep level mining operations
Defence problems related to high velocity impact
Structural failure predictions for impact
Seismic and blast loading
