Modeling Simultaneous Multiple Fracturing Using the Combined Finite-Discrete Element Method [PDF]
Geofluids, 2018 Simultaneous multiple fracturing is a key technology to facilitate the production of shale oil/gas. When multiple hydraulic fractures propagate simultaneously, there is an interaction effect among these propagating hydraulic fractures, known as the ...

Nonlinear analysis of engineering structures by combined finite-discrete element method [PDF]
Građevinar, 2013 A numerical model for dynamic analysis of dry-stone masonry and reinforced-concrete structures, based on the combined finite-discrete element method (FEM/DEM), is presented in the paper.

HOSS: an implementation of the combined finite-discrete element method [PDF]
Computational Particle Mechanics, 2020 AbstractNearly thirty years since its inception, the combined finite-discrete element method (FDEM) has made remarkable strides in becoming a mainstream analysis tool within the field of Computational Mechanics. FDEM was developed to effectively “bridge the gap” between two disparate Computational Mechanics approaches known as the finite and discrete ...

A FDEM Parametric Investigation on the Impact Fracture of Monolithic Glass
Buildings, 2022 Due to the brittleness, monolithic glass may fracture under impact, resulting in catastrophic sequences. The combined finite-discrete element method, i.e., FDEM, is employed to investigate both the oblique and the perpendicular impact failures of ...

Convergence analysis of two-grid methods for second order hyperbolic equation
Journal of Inequalities and Applications, 2021 In this paper, a second-order hyperbolic equation is solved by a two-grid algorithm combined with the expanded mixed finite element method. The error estimate of the expanded mixed finite element method with discrete-time scheme is demonstrated. Moreover,
