Aplicação de modelos de quebra de partículas do ambiente de simulação do método dos elementos discretos no estudo de microprocessos de cominuição
… microprocesses were studied using three particle breakage models within the DEM simulation environment: The Bonded Particle Model – BPM, the Fast Breakage Model - FBM, and the Particle Replacement Model – PRM. Such models were calibrated on the basis of the median fracture energy of …

Distict element numerical modelling of volcanic debris avalanche emplacement geomechanics.
… are then used to develop a general emplacement model which summarizes the geomechanical evolution of VDAs. This model is then tested by analyzing orthophotographic images of VDA deposits; common deposit morphologies are observed in each case, suggesting a common deformation sequence may occur …

Investigation of unstable failure in underground coal mining using the discrete element method
… of a western U.S. coal. Two discrete element models are evaluated for their ability to simulate unstable and stable compressive failure using the discrete element program Particle Flow Code in Two Dimensions (PFC2D): the bonded particle model and the displacement softening model. Compressive …

A study of impact breakage of single rock specimen using discrete element method
… processing which aims to reduce the size of ore particles through breakage, consequently increasing the likelihood of the liberation of valuable minerals. However, comminution is highly energy-intensive and an understanding of the key breakage mechanisms has been identified as an important factor …
