A Novel Mixed-Mode Power Exponent Cohesive Zone Model for FDEM and Its Application to Tunnel Excavation in the Layered Rock Mass

To investigate the asymmetric failure mechanism and failure mode of layered rock tunnels, a novel mixed-mode power exponent cohesive zone model (M-PECZM) is proposed in this paper, which can capture the crack propagation process under single-mode loading, tension-shear loading, and compression-shear...
