摘要：
In this paper, the fatigue failure of engineered cementitious composites (ECC) and concrete laminated structure was investigated by using a model based on the peridynamics (PD) method. The model enhances efficiency by incorporating "residual life" and "cyclic blocks," utilizing the fully discrete method for ECC interfaces and the energy-based PD model for bimaterial interfaces. Its effectiveness, accuracy, and versatility have been validated through various numerical examples. Furthermore, the study examines crack propagation in ECC pavement overlays under four-point bending and investigates the impact of ECC layer thickness and fiber content on the fatigue characteristics of laminated structures.
