Numerical simulation of rock slope failure with dynamic frictional contact based on co-rotational technique

Based on the co-rotational formulation to deal with large displacements and rotations of a solid, we propose a method of numerical simulations of rock slope failure involving dynamic frictional-contact behavior. In order to simulate failure process of a rock slope subjected to external loading such as an earthquake, we divide the phenomena into multiple stages. The proposed method enables us to represent all of these deformation and failure stages in a continuous fashion. Some simple numerical examples are presented to demonstrate the capability of the proposed method to simulate multi-stage failure processes.
