dynamic modeling of a rock crushing process

Evaluation of Disc Cutter Performance in Rock Cutting
numerical modeling methods using FEM dynamic analysis. Numerical methods can be used to estimate the force required to cut the rock which can simplify predicting the TBM penetration rate by simulating the rock fracture process. Cook et al. 2 compared the results of wedge-induced rock crushing by 2D FEM modeling

Nonlinear dynamic characteristics of load time series in
In rock cutting process the time series of a typical load signal was collected as shown in Fig. 2. The extrusion of the cutter on the rock at the initial stage produced a crushing zone and the cutting load increased nonlinearly along with penetration displacement.

Thermal shock weakening of granite rock under dynamic
rock originally presented by Saksala et al. 15 16 is further developed for modeling the rock fracturing under combined dynamic loading and thermal shock. On the one hand the coupled thermomechanical problem underlying the plasma jet-induced damage/cracking of rock appears to be reducible to an uncoupled problem due to the highly dominating

Numerical modeling of the emplacement of Socompa rock
1 The 7.5 ka Socompa sector collapse emplaced 25 km 3 of fragmented rock as a thin but widespread (500 km 2) avalanche deposit followed by late stage sliding of 11 km 3 as Toreva blocks. Most of the avalanche mass was emplaced dry although saturation of a basal shear layer cannot be excluded. Modeling was carried out using the depth-averaged granular flow equations in order to

Discrete Element Modeling of Dynamic Compaction with
Dynamic Compaction (DC) is a common deep compaction method that is usually used for densification of coarse-grained soils. Although traditional continuum-based models such as the Finite Element Method can be successfully applied for assessment of stress distributions or deformations induced by DC they are typically not adequate for capturing the grain scale mechanisms of soil behavior under

Numerical simulation of rock fragmentation process by
A numerical model of rock fragmentation caused by a roadheader pick was established based on the particle flow code in two dimensions to study the rock fragmentation mechanism of the roadheader pick. The model simulated crack initiation propagation and chip formation. The feasibility and reliability of the method as well as numerical model were verified by experiment.
