- Discrete element modeling of explosion-induced fracture extension in . . .
The study employs discrete element modeling to simulate explosion-induced fracture propagation in jointed rock masses Dynamic fracture extension occurs in two modes: from pre-existing fractures and newly formed cracks in intact rock
- Modelling of blast-induced fractures in jointed rock masses
This paper focuses on the dynamic fracturing process of jointed rock masses due to blast wave loading A coupled numerical method using both LS-DYNA (a transient dynamic finite element program) and UDEC (an universal discrete element code) is outlined first
- Discrete element modeling of explosion-induced fracture extension in . . .
In this work, the process of extension of blast-induced fractures in rock masses is simulated using the discrete element method It should be noted that, in this work, fracture propagation from both the rock mass inherent fractures and newly induced cracks are considered
- Discrete element modeling of explosion-induced fracture extension in . . .
Discrete element modeling of explosion-induced fracture extension in jointed rock masses Lak, M; Marji, MF; Bafghi, ARY; Abdollahipour, A Marji, MF (reprint author), Yazd Univ, Fac Min Met Engn, Yazd, Iran JOURNAL OF MINING AND ENVIRONMENT, 2019; 10 (1): 125 Abstract
- Damage Development in Double Hole Blasting of Randomly Jointed Rock . . .
This work offers a reliable numerical approach and practical guidance for designing jointed rock blasting, optimizing cutting parameters, and supporting engineering applications
- FDEM modeling of the fracture, fragmentation and collapse process of . . .
The blasting-induced stress redistribution and the corresponding rock fracture, fragmentation and collapse process on site are simulated, which vividly replicate the formation of smooth tunnel sidewalls and the occurrence of rock collapse at the tunnel crown area incorporating pre-existing joints
- Discrete element modeling of explosion-induced fracture extension in . . .
In this work, the process of extension of blast-induced fractures in rock masses is simulated using the discrete element method It should be noted that, in this work, fracture propagation from both the rock mass inherent fractures and newly induced cracks are considered
- Modelling of blast-induced fractures in jointed rock mass
By using a coupled FEM-DEM approach, the dynamic rock fracturing process of jointed rock masses under blasting was numerically investigated by Wang and Konietzky [10], who concluded that
- Modelling of blast-induced fractures in jointed rock masses,Engineering . . .
A coupled numerical method using both LS-DYNA (a transient dynamic finite element program) and UDEC (an universal discrete element code) is outlined first The blast-induced fracture extension in two representative jointed rock masses is studied subsequently
- Modeling Blast-Induced Fragmentation of Jointed Rock Mass Using Voronoi . . .
The present study developed a model for the estimation of blast-induced fragmentation using a discrete-element method coupled with image processing techniques In the numerical model, Voronoi elements were used to simulate microcracks of rock materials
