FDEM simulation for granular materials based on exact scaling and coarse granulation

open access: yesYantu gongcheng xuebao
The particle materials are characterized by discontinuity and dispersion, so they face great computational pressure in numerical simulation. The exact scaling criterion and coarse-grained method are introduced into the combined finite-discrete element ...

Space Decomposition Based Parallelisation Solutions for the Combined Finite-Discrete Element Method in 2D. [PDF]

open access: yes, 2015
PhDThe Combined Finite-Discrete Element Method (FDEM), originally invented by Munjiza, has become a tool of choice for problems of discontinua, where particles are deformable and can fracture or fragment.

Sažetak [PDF]

open access: yes, 2018
This paper presents a new numerical model for the analysis of beam type structures. The model uses two-noded rotation free finite elements and takes into account material non-linearity, finite displacements, finite rotations and finite strains.

Excavation-induced fracturing mechanisms in deep hard rock: A hierarchical block model

open access: yesUnderground Space
The fracture characteristics of the excavation damage zones (EDZs) of deeply buried tunnels are closely related to energy evolution, and they are highly valuable for support design.

When cracks look different [PDF]

open access: yes, 2013
In this work, by means of numerical experiments based on Los Alamos National Laboratory’s combined finite discrete element method (FDEM) software package MUNROU, it is demonstrated that fracture patterns do not only depend on the solid properties, but ...

Numerical analyses of pillar behavior with variation in yield criterion, dilatancy, rock heterogeneity and length to width ratio

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2019
With recent advances in numerical modeling, design of underground structures increasingly relies on numerical modeling-based analysis approaches. While modeling tools like the discrete element method (DEM) and the combined finite-discrete element method (

A new thermomechanical coupled FDEM model for geomaterials considering continuum-discontinuum transitions [PDF]

open access: yes
A new thermomechanical (TM) coupled finite-discrete element method (FDEM) model, incorporating heat conduction, thermal cracking, and contact heat transfer, has been proposed for both continuous and discontinuous geomaterials.
