A combined finite‐discrete element method in transient dynamics of fracturing solids
Engineering Computations, 1995This paper discusses the issues involved in the development of combined finite/discrete element methods; both from a fundamental theoretical viewpoint and some related algorithmic considerations essential for the efficient numerical solution of large scale industrial problems.

The Combined Finite‐Discrete Element Method
2004The combined finite discrete element method is a relatively new computational tool aimed at problems involving static and / or dynamic behaviour of systems involving a large number of solid deformable bodies. Such problems include fragmentation using explosives (e.g rock blasting), impacts, demolition (collapsing buildings), blast loads, digging and ...

Combined Finite-Discrete Element Method for Simulation of Hydraulic Fracturing
Rock Mechanics and Rock Engineering, 2015Hydraulic fracturing is widely used in the exploitation of unconventional gas (such as shale gas).Thus, the study of hydraulic fracturing is of particular importance for petroleum industry. The combined finite-discrete element method (FDEM) proposed by Munjiza is an innovative numerical technique to capture progressive damage and failure processes in ...

The combined finite-discrete element method for structural failure and collapse
Engineering Fracture Mechanics, 2004A combined finite–discrete element model for failure and collapse of structural systems comprising of reinforced concrete beam or column type structural members has been developed and implemented into a combined finite–discrete element code. The results obtained using the proposed model compare well with analytical and experimental results. In addition

International Journal for Numerical Methods in Engineering, 2009
AbstractIn the past, the combined finite–discrete element was mostly based on linear tetrahedral finite elements. Locking problems associated with this element can seriously degrade the accuracy of their simulations. In this work an efficient ten‐noded quadratic element is developed in a format suitable for the combined finite–discrete element method ...

A model for thin shells in the combined finite-discrete element method
Engineering Computations, 2018Purpose This paper aims to present a new numerical model for geometric nonlinear analysis of thin-shell structures based on a combined finite-discrete element method (FDEM). Design/methodology/approach The model uses rotation-free, three-node triangular finite elements with exact formulation for large rotations, large displacements in conjunction ...

Combined Finite-Discrete Element Method Modeling of Rock Failure Problems
2016The purpose of this paper is to propose a novel combined finite-discrete element method (FDEM), based on the cohesive zone model (CZM), for simulating rock failure problems. The rock mass is represented as a collection of elastic bulk elements glued by cohesive elements with zero thickness.
