Introduction
My research involves simulating real materials on a computer to unveil the physical phenomena that can help solving industrial problems, optimise processes and lead to new discoveries in material science.

Article
Full-text available
New engineered materials have critical applications in different fields in medicine, engineering and technology but their enhanced mechanical performances are significantly affected by the microstructural design and the sintering process used in their manufacture. This work introduces (i) a methodology for the calculation of the full deflection pro...
Conference Paper
Full-text available
The combined finite-discrete element method (FEMDEM) implemented in Solidity is employed to simulate the effects of geometrical features and loading orientation on the pre- and post-failure behaviour of catalyst supports. In this paper, a comparison with experimental results and a mesh sensitivity analysis for the numerical simulations of uniaxial...
Article
The effects of catalyst support shapes on their final strength and fragmentation behaviour are investigated. Uniaxial compression tests by diametrical loading of solid and four-holed discs with high-speed video recordings are employed to investigate strengths and pellet crushing behaviours. The combined finite-discrete element method (FDEM) is empl...
Article
Full-text available
The application of the combined finite-discrete element method (FDEM) to simulate fracture propagation in fibre-reinforced-concrete (FRC)-lined tunnels has been investigated. This constitutes the first attempt of using FDEM for the simulation of fracture in FRC structures. The mathematical implementations of the new FDEM joint-element constitutive...
Article
A new rigid component of the combined finite-discrete element method (FDEM) is employed to estimate the effects of geometrical features, friction and energy dissipation parameters on the bulk properties of rigid pellet packs. This work constitutes the first systematic validation of the Solidity FDEM code for rigid particles. The experimental and nu...
Article
Full-text available
In many granular material simulation applications, DEM capability is focused on the dynamic solid particulate flow properties and on systems in which millions of particles are involved. The time of relevance is many seconds or even minutes of real time. Simplifying assumptions are made to achieve run completion in practical timescales. There are ce...
Conference Paper
A number of numerical algorithms for simulation of particle packing have been proposed and used in a wide range of industries: mining, chemical engineering, pharmaceuticals, agriculture and food handling, etc. However, most of them can only deal with simple and regular shapes due to the complex and expensive numerical algorithms needed to simulate...
Conference Paper
Catalyst pellets are packed in reactor beds and the shape and mechanical properties have a major influence on the reactor performance by virtue of (i) the detailed topology of the void space and grain surface area and (ii) the fragility of the pack to withstand in-service stresses within the solid skeleton—often through thermal and cyclic stressing...

Conference Paper
Full-text available
Alumina (aluminum oxide, Al 2 O 3) particles are pelletised and fired to produce high porosity catalyst pellets of complex shapes. These pellets fill cylindrical reactor columns with particulate packing structures that are key to the in-service performance, but will suffer breakages which impact on catalyst performance. The combined Finite-Discrete...

The research will investigate application of the combined finite-discrete element method (FEMDEM) to simulate fracture propagation in fibre-reinforced-sprayed-concrete (FRSC) tunnel linings. This research will define a new joint-element constitutive model for FRSC, validate the software, and apply it to a practical tunnel design case study. The final aim is better understand the post-crack behaviour of Sprayed Concrete Lined (SCL) tunnels.
