Cross-configuration assessment of functionally graded adhesives in single-lap joints via an elastoplastic ductile-damage framework

Key Points

• Mechanical performance of functionally graded adhesives significantly affects joint durability, impacting overall structural reliability.
• Key evidence shows optimized elastoplastic properties lead to lower failure rates in single-lap joints under stress.
• Assessment using the elastoplastic ductile-damage framework enables insights into failure mechanisms of these joints.
• Highlights the need for more extensive research to validate these findings across varied conditions and materials.
