Abstract Scope |
This work is a continuation of the preliminary project with the investigation of the characteristics of the cellular structure-based mechanical interlocking interface designs for bi-material structures fabricated by material extrusion additive manufacturing (AM). Three different cellular designs, including auxetic, body centered cubic (BCC), and octahedral, were investigated for the topology design effects on the interface performance. In addition, the effects of build orientation and interface polarity were also studied. The results clearly suggested that the cellular-based mechanical interlocking interface exhibit significantly enhanced ductility and energy absorption that can be desirable to many applications, and that the interface characteristics are influenced by both the topology design of the cellular structures and the intrinsic properties of the processed materials. |
