Abstract

A Hybrid finite-discrete element Method is introduced to simulate fracture and fragmentation processes of Brazilian disc test. The transition from continuum to discontinuum through fracture and fragmentation is implemented through a combined single and smeared crack model. An integrated development environment i.e. Y-2D/3D IDE, which incorporates the hybrid finite-discrete method and the combined single and smeared crack, is used to model the fracture and fragmentation process of Brazilian disc test. It is found that the proposed method, i.e. Hybrid finite-discrete element method, reproduces the processes of stress initiation and propagation, the fracture process and resultant fragments of rock in the Brazilian disc tests. The modelled failure patterns agree well with documented tests. It is concluded that the Hybrid finite-discrete method demonstrates its capability in modelling the behaviors of Brazilian disc under static loading rates.
