The combined plastic and discrete fracture deformation framework for finite‐discrete element methods
International Journal for Numerical Methods in Engineering, 2019SummaryThe combined finite‐discrete element method (FDEM) was originally developed for fracture and fragmentation of brittle materials, more specifically for cementitious and rock‐like materials. In this work, a combination of a discrete crack and plastic deformation has been combined and applied to FDEM simulation of fracture.

Recent Developments in the Combined Finite-Discrete Element Method
2015Discontinua modeling techniques, such as Discrete Element Method (DEM), Discontinuum Deformation Analysis (DDA), Combined Finite-Discrete Element Method (FDEM) and Numerical Manifold Method (NMM) have become important analysis tools within the Computational Mechanics field.

Numerical analysis of masonry structures by combined finite-discrete element method
2021Building construction using stone or clay bricks that are held together by mortar is one of the oldest building techniques that is still in use today. Among the oldest construction are masonry stone huts in a form of a circle found nearby lake Hullen in Israel that come from a period between 9.000 and 8.000 BC [1].

Fracture and fragmentation of thin shells using the combined finite–discrete element method
International Journal for Numerical Methods in Engineering, 2013SUMMARYA model for fracture and fragmentation of multilayered thin shells has been developed and implemented into the combined finite–discrete element code. The proposed model incorporates an extension of the original combined single and smeared fracture approach to multilayered thin shells; it then combines these with an interaction algorithm that is ...

Combined single and smeared crack model in combined finite-discrete element method
International journal for numerical methods in engineering, 1999Large‐scale discrete element simulations, combined finite‐discrete element simulations as well as a whole range of related problems, involve a large number of separate bodies that interact with each other and in general deform and fracture. In this context there is a need for a robust fracture algorithm applicable to simultaneous multiple fracturing of

58th U.S. Rock Mechanics/Geomechanics Symposium
ABSTRACT: Simulating the structural response of concrete and reinforced concrete structures to blast loading conditions is a challenging task, as it requires modeling the fracture and fragmentation processes in this composite material with reasonable computational efficiency for large scale simulations.

Numerical simulations of impacts using combined finite-discrete element method
2012One of very interesting problem in civil engineering applications is reinforced concrete structures subjected to impact load which are often used in protective purpose. Frag- mentation that may occur during impact cannot be modelled by the continuum methods.
