... Abstract Rock failure progressive processes in static tests and dynamic impact tests are modelled using a hybrid finite-discrete element method. The simulated results are then compared with these recorded in literatures to calibrate the hybrid method. After that, the hybrid finite-discrete...

... Abstract DDA belongs to the family of Discrete Element Method (DEM). It is an implicit version of DEM. Unlike its sister method, Distinct Element Method, proposed by Cundall and has been developed over the years, DDA received less attention, especially for its application to simulate fluid...

... to represent the cracks once they appear in a continuum medium. An example is the joint element (Goodman et al. 1968, Lotfi 1992) used in the finite element method. How- ever, this approach can only take a few cracks into consideration. The other one, from the perspective of non-continuum mechanics...

... Abstract As distinguished from the former types of toppling failure (i.e. flexural, blocky, blocky-flexural and secondary), another type of toppling failure developed in interbedded hard rock and soft rock slope is very common in Three Gorges Reservoir region. Based on discrete element method...
