Rock Bridge Fracture and Differential Deformation During Progressive Failure of Rock Slopes with Intermittent Joints Using a Stabilized Peridynamics Model

Progressive failure of rock slopes with intermittent joints involves crack propagation through intact rock bridges and the development of differential deformation. This study uses a stabilized non-ordinary state-based peridynamics model to investigate these processes. The model c...

A Cover-based Enhanced Direct Search Approach for Contact Detection of Convex Polyhedral Blocks and Its Application with 3D DDA

In implicit numerical simulation of block systems, the establishment of complete inequality constraints and the accurate enforcement of contact constraints are fundamental issues. However, the conventional direct search (DS) method is usually based on a local type identification...
