Permanent Connections
handbooks [5, 9]. Usually, adhesives with adequate ductility are preferred for reducing 115
stress concentration and increasing toughness to resist debond propagation [1].
Since peel stresses focus at bond ends, increasing bonded area or utilizing rivets at
bond ends can effectively reduce debonding failure and significantly improve durability
and reliability of adhesive joints.
