Abstract and subjects
Additive manufacturing (AM) has provided a new paradigm of control not only on material microstructure but also on 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 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 chapter will provide an overview of the dynamic behaviors of additively manufactured polymers and metals and provide a perspective on future directions in the area.
