| Abstract: |
Focusing on fatigue cracks initiated at in-plane gusset welded joints, the delay in crack growth life due to externally bonded CFRP was experimentally verified. The results indicate that CFRP prevents the release of residual stress, subsequently delays crack growth in the compressive residual stress area. |
