Numerical Cohesive Zone Modeling (CZM) of Self-Anchoring AM Metal-CFRP joints

Frattura ed Integrità Strutturale
The escalating importance of lightweight design in engineering demands innovative strategies to tackle this challenge. Traditionally, the joining of these materials involves rivets, bolts, or adhesives. However, contemporary manufacturing techniques, such as 3D printing, present the potential to fabricate joints without the necessity for additional ...
