Investigation of different discrete modeling strategies to mimic microstructural aspects that influence the fracture energy of refractory materials Open
The mismatch between the coefficient of thermal expansion of the constituents within refractory ceramics could advantageously be used to tune the fracturing behavior by inducing numerous microcracks within the microstructure. The Wedge Spl…

Discrete element modelling of ordinary refractory ceramics under cold crushing testing: Influence of minimum element size Open
Ordinary refractory ceramics comprise aggregates and fines of different sizes. Reasonable representation of fines in discrete element models is important for computation efficiency and obtaining representative results. In this study, diffe…

Numerical Modelling of The Quasi-Brittle Behaviour of Refractory Ceramics by Considering Microcracks Effect Open
In the steelmaking industry, the inner lining of ladles is made of refractory ceramics, which are constantly subjected to thermal shocks during their service. Experimentally, it is observed that pre-existing microcracks could significantly…

Distinct element geomechanical modelling of the formation of sinkhole clusters within large-scale karstic depressions Open
The 2-D distinct element method (DEM) code (PFC2D_V5) is used here to simulate the evolution of subsidence-related karst landforms, such as single and clustered sinkholes, and associated larger-scale depressions. Subsurface material in the…

Geomechanical modelling of sinkhole development using distinct elements: model verification for a single void space and application to the Dead Sea area Open
Mechanical and/or chemical removal of material from the subsurface may generate large subsurface cavities, the destabilisation of which can lead to ground collapse and the formation of sinkholes. Numerical simulation of the interaction of …
