Abstract

The structural dynamic behavior of 3D-printed and conventional aluminum alloys are studied experimentally. Heat treated Scalmalloy and Al 7075 T-6 beam-like structures are fabricated using additive and extrusion manufacturing, respectively. The beams are exposed to vibration fatigue. Linear and nonlinear dynamic characterizations are performed to extract the stiffness and damping properties for pristine and fatigued structures. Additionally, the study includes optical imaging, Electron Backscatter Diffraction (EBSD), and Atomic Force Microscopy (AFM) to obtain the alloys’ materials properties. While the preliminary results show that Scalmalloy fatigue life is approximately 3-4 times lower than Al 7075 T-6, failure in Scalmalloy appears to be more graceful and predictable than that for aluminum.
