“…Both 2D and 3D FEM are widely used to solve 2D and 3D dimensional problems. In the field of rock mechanics, various numerical simulation codes, such as LS-DYNA [3,4,12,13,[15][16][17][18], ABAQUS [14], and rock failure process analysis (RFPA) [19][20][21][22][23][24][25][26][27][28][29], have been used for modeling. As shown in Table 1, LS-DYNA was widely used by scholars to simulate rock-tool interaction.…”

“…RFPA, which was developed by the Northeastern University of China, is a professional rock failure analysis tool and has been widely used to analyze 2D rock failure problems in recent years. As a scientific research team, Tang and his partners have performed many studies on rock fragmentation mechanism, simulating the progress of rock cutting using RFPA (2D) [19][20][21][22][23][24][25][26][27][28][29]. DEM is a numerical method for simulating a discontinuous medium, and it is widely used in slope stability, tunnel excavation, and rock dynamic behavior simulations.…”

“…It was noted that particle shape not only governs breakage strength, but also influences the macro behaviours of railway ballast (Tang et al 2001, Lim and McDowell 2005, Cho et al 2006. With the finite element method, Tang et al (2001) simulated a 2-D single particle breakage, and reported that the more spherical the particles are, the higher the breakage strength is. Hence, it is necessary to take into account the particle shape in the DEM modelling of ballast breakage.…”

“…Fragmentation is an important environmental issue as it is both an energy intensive process and a producer of significant quantities of fine waste and airborne dust. Reduction of the energy consumption used to generate fragmentation and control over the product size ranges produced can therefore bring both economic and environmental benefits [2,3].…”

“…General dynamic fragmentation papers are presented by a range of authors [4][5][6][7][8][9][10]. Rock crushing is addressed in papers [2,[11][12][13][14][15], rock cutting in [16] and blasting in papers [18][19][20][21][22].…”
