| الوصف: | Fused deposition modeling (FDM) is a standard 3D printing technique used regularly in high performance and consumer level printers. FDM involves extruding heated thermoplastic filament in multiple layers. When two print heads with dissimilar filaments are used in coordination with one another, alternating print layers, multi-material structures can be designed to exhibit tuned dynamic behavior at the flexible / rigid multi-material interface. Joints tailored with specific stiffness and damping properties have applications in a wide range of fields, including vibration and acoustic isolation. While compliant, flexible materials used in multi-material FDM printing have intrinsic material damping associated with the mechanical energy dissipation within each individual material, additional structural damping resulting from poor material interfaces can also arise in these types of applications. Measurement of this damping can provide a non-destructive means of identifying poor interface joints. Appropriate measurement of both forms of damping are important for tuning compliant joints to the desired dynamic behavior as well as identifying flaws within the interfaces. Several different methods for modeling and measuring damping in multi-material compliant joints will be described, and comparison of experimentally measured damping will be presented for material damping alone, and material damping combined with structural damping resulting from different material interfaces. |
