MODELING THE BRAZILIAN TENSILE STRENGTH TEST OF LIGNITE FROM PESTEANA OPENPIT MINE USING THE COMBINED FINITE-DISCRETE ELEMENT METHOD – FDEM [PDF]

open access: yesFiabilitate şi Durabilitate, 2023
Strength is the property of rocks to keep their internal structure unmodified and not deform under the action of a stress. Tensile strength is defined as the maximum tensile stress the rock can endure until its failure and it is usually lower than ...

MODELING OF THE UNCONFINED COMPRESSIVE STRENGTH TEST OF LIGNITE FROM PESTEANA OPENPIT MINE USING THE COMBINED FINITE-DISCRETE ELEMENT METHOD – FDEM [PDF]

open access: yesFiabilitate şi Durabilitate, 2023
The property of rocks to oppose and keep their shape almost unchanged under the action of load is called strength. Compressive strength is defined as the maximum stress a material can withstand until its failure. Besides the physical characteristics of

Space decomposition based parallelization solutions for the combined finite–discrete element method in 2D

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2014
The combined finite–discrete element method (FDEM) belongs to a family of methods of computational mechanics of discontinua. The method is suitable for problems of discontinua, where particles are deformable and can fracture or fragment. The applications
