Abstract
This paper presents an accelerated phase-field method combining an adaptive cycle increment adjustment algorithm and Phase-Field Cohesive Zone Model (PF-CZM) to simulate High-Cycle Fatigue (HCF) of quasi-brittle materials. Based on an asymptotic fatigue degradation function extended to fatigue behaviour, the analogy between accumulated history variables and damage variables is used. Acceleration is achieved by deeming the accumulated history variable in the fatigue degradation function as a damage variable. The cycle increment is associated with the increment of the accumulated history variable based on experimental data. In order to improve computational efficiency, the entire fatigue simulation process is divided into three stages, and different cycle increments are applied to each stage. In order to demonstrate the effectiveness of the proposed accelerated phase-field scheme, comprehensive verification is conducted with experimental results and previous cycle-by-cycle numerical results, including mode I crack propagation and mixed mode I + II crack propagation, highlighting the efficiency and robustness of the proposed method. In addition, the influence of phase-field length scale on the crack pattern of concrete is studied. The fatigue behaviour of both 2D and 3D structures are showcased by applying the proposed model.
