“…This method can be used in two and three dimensions and for dynamic (flow) problems but is limited to spherical particles as the internal one-dimensional approximation of the temperature field is only valid for spherical particles. Recently, [53]have used finite discrete element method (FDEM) to study intra-particle heat transfer in granular assemblies allowing for complex temperature fields to be resolved within complex shaped multi-bodied contact problems. While this does extend FEM beyond static problems, the size of the systems that can be analyzed are still limited to a few thousand with fairly long run times.…”

“…DEM has been proven to be more suitable tool than Finite Element Method (FEM) and Finite Volume Method (FVM) to simulate compaction [45,46]. Some researchers have also used the hybrid approaches-a combination of Finite-Discrete Element Methods-FDEM to analyze geomechanical problems [25,[47][48][49][50][51][52][53]. FDEM and Y-Geo software, despite their limitations (mesh sensitivity, lack of hydro-mechanical coupling and fluid propagation in the cracks, long computational times), has effectively simulated complex rock slope instability problems from triggering, initiation, evolution, run out and deposition processes [47,54].…”

Granular matter is ubiquitous in our daily life yet far from completely understood. These granular materials have constituted a class of complex systems which exhibit global behaviors been reminiscent of solids, liquids, gases, or otherwise uniquely their own. The key to achieve good properties lies in the material structure from the molecules, via structures on nano and micro levels to the macroscopic material. This paper also reviewed selected approaches and models that have been developed for granular media prediction. However, development of new approaches at the micro and nano scales to sense the stress distribution characteristics of complex rock media, especially the grounds bearing petroleum resources of Nigeria has been of vital concern/importance to the area of petroleum drilling and exploration. By conducting such fundamental level research, development of highly efficient drilling processes with potentially much less energy inputs and minimizing the carbon blue prints is the best approach.

Simulation of fracture propagation in fibre-reinforced concrete using FDEM: an application to tunnel linings

The application of the combined finite-discrete element method (FDEM) to simulate fracture propagation in fibre-reinforcedconcrete (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 model are first introduced, and the numerical model is then validated comparing the results for plain and FRC beams with three-point bending experimental data. The code has also been applied to two practical tunnel design case studies, showing different behaviours depending on the type of concrete and shape of tunnel section. The FDEM simulations of the linings are also compared with results from a finite element code that is commonly used in the engineering design practise. These results show the capabilities of FDEM for better understanding of the fracture mechanics and crack propagation in FRC tunnels. A methodology for directly inferring the numerical parameters from three-point bending tests is also illustrated. The results of this research can be applied to any FRC structure.Keywords Numerical simulation · Combined finite-discrete element method · Joint-element constitutive model · Three-point bending test
