Dynamic Behavior of Additively Manufactured Materials
Additive manufacturing (AM) has provided a new paradigm of control not only of material microstructure but also of structural assembly. The promise of AM lies in tailoring properties through this exquisite microstructural and topological design and fabrication, and the possibility of “metamaterial” properties simply not possible through most conventional manufacturing. Relevant to mechanical properties and dynamic performance, the application of AM has resulted in many examples in which control of deformation mechanics and structural instabilities has led to novel properties, such as high strength-to-weight ratios, tailored thermal management, and auxetic properties. This talk will provide an overview of the dynamic behaviors of additively manufactured metals and polymers, and provide a perspective on the current challenges in AM for dynamic loading environments and future directions in the area.
