Discrete element modeling of tool-rock interaction I: rock cutting
TL;DR: In this article, numerical simulations of the cutting process are conducted to reproduce the transition from a ductile to a brittle failure mode with increasing depth of cut, which is observed in experiments.

Advances in the particle finite element method for the analysis of fluid-multibody interaction and bed erosion in free surface flows
TL;DR: In this article, the particle finite element method (PFEM) is used for solving complex fluid-structure interaction problems with free surface waves, such as splashing of waves, large motions of floating and submerged bodies and bed erosion.

Discrete element simulation of rock cutting
TL;DR: In this article, a tool-rock system is modeled using the discrete element method, which is suitable to study problems of multiple material fracturing such as those involved in rock cutting, and the results of the 2D and 3D analyses are compared with one another, and numerical results have been compared with available experimental data.

Calibration of a discrete element model for intact rock up to its peak strength
Yuannian Wang,Fulvio Tonon +1 more
TL;DR: In this article, the authors used sensitivity analysis to identify the deformability micro parameters by obtaining relationships between microscopic and macroscopic deformability properties, and then the strength model parameters were identified by a global optimization process aimed at minimizing the difference between computed and experimental failure envelopes.

Discrete numerical model for granular assemblies.
Peter Cundall,Otto D. L. Strack +1 more
TL;DR: The distinct element method as mentioned in this paper is a numerical model capable of describing the mechanical behavior of assemblies of discs and spheres and is based on the use of an explicit numerical scheme in which the interaction of the particles is monitored contact by contact and the motion of the objects modelled particle by particle.

Contact and Rubbing of Flat Surfaces
TL;DR: In this article, the authors compared the deduced dependence of the experimental observables on the load with the experimental evidence and concluded that the most realistic model is one in which increasing the load increases both the number and size of the contact areas.
