文摘
- •
Fatigue property of three-sheet spot weld-bonded joints was studied.
- •
Fatigue strength was improved by combining spot-welding and adhesive-bonding.
- •
Fatigue crack initiation was delayed because of stress reduction by adhesive.
- •
The delayed fatigue crack initiation resulted in the fatigue strength improvement.
