Abstract

Vibration suppression in a field of frequencies and the creation of band gaps which do not allow the propagation of the waves is studied in this paper by means of microstructures designed through topology optimization. Topology optimization is formulated in frequency domain. Band gap design is based on Floquet-Bloch theory and genetic optimization. The result is appealing in view of modern 3D printing techniques.

Subject Areas

vibration suppression; topology optimization; band gaps; Bloch theory; finite element analysis (List three to ten pertinent keywords specific to the article; yet reasonably common within the subject discipline.)
