Surface reconstruction with spherical harmonics and its application for single particle crushing simulations

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2022
Particle morphology has great influence on mechanical behaviour and hydro/thermal/electrical conductivities of granular materials. Surface reconstruction and mesh generation are critical to consider realistic particle shapes in various computational ...

Combined Finite–Discrete Numerical Modeling of Runout of the Torgiovannetto di Assisi Rockslide in Central Italy [PDF]

open access: yes, 2016
The combined finite–discrete-element method (FDEM) is an advanced and relatively new numerical modeling technique that combines the features of the FEM with those of the discrete-element method.

GPU based parallel FDEM for analysis of cable structures

open access: yesGrađevinar, 2017
A combined finite-discrete element method, adapted for the analysis of a parallel cable element model using graphic cards, is presented in the paper. The basic objective is to speed up sequential computation time by one or two orders of magnitude.

Three-Dimensional Combined Finite-Discrete Element Modeling of Shear Fracture Process in Direct Shearing of Rough Concrete–Rock Joints

open access: yesApplied Sciences, 2020
A three-dimensional combined finite-discrete element element method (FDEM), parallelized by a general-purpose graphic-processing-unit (GPGPU), was applied to identify the fracture process of rough concrete–rock joints under direct shearing.

A combined remote sensing–numerical modelling approach to the stability analysis of Delabole Slate Quarry, Cornwall, UK [PDF]

open access: yes, 2015
The final publication is available at Springer via http://dx.doi.org/10.1007/s00603-015-0805-zRock slope geometry and discontinuity properties are among the most important factors in realistic rock slope analysis yet they are often oversimplified in ...

Numerical simulation of hydraulic fracturing and associated microseismicity using finite-discrete element method

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2014
Hydraulic fracturing (HF) technique has been extensively used for the exploitation of unconventional oil and gas reservoirs. HF enhances the connectivity of less permeable oil and gas-bearing rock formations by fluid injection, which creates an ...

MODELING THE BRAZILIAN TENSILE STRENGTH TEST OF LIGNITE FROM PESTEANA OPENPIT MINE USING THE COMBINED FINITE-DISCRETE ELEMENT METHOD – FDEM [PDF]

open access: yesFiabilitate şi Durabilitate, 2023
Strength is the property of rocks to keep their internal structure unmodified and not deform under the action of a stress. Tensile strength is defined as the maximum tensile stress the rock can endure until its failure and it is usually lower than ...

Analysis of Extent of Deformation Range and Failure Characteristics of Rocks Surrounding a Tunnel Crossing Fault Zone Based on FDEM

open access: yesAdvances in Civil Engineering, 2022
The combined finite-discrete element method (FDEM) and laboratory test were selected to study the extent of deformation range and time-dependent deformation of surrounding rock during tunnel excavation without support in a fault-crossing tunnel project ...
