摘要：

This paper proposes an extended finite element method (XFEM) modelling approach coupled with cyclic damage mechanics criteria to simulate the fatigue crack growth (FCG), progressive delamination, and bridging in metal-fibre reinforced polymer (FRP) composites. The FCG in the metal is described using linear elastic fracture mechanics. The cycle-by-cycle degradation of the adhesive layer, progressive damage in the FRP layers, and metal-FRP interface delamination are modelled using the damage mechanics criteria. The proposed XFEM model successfully simulates the fatigue behaviour of FRP-strengthened metallic plates. The FCG rates, crack trajectories, fatigue lives, and failure modes satisfactorily agree with the corresponding experimental data.
