Bloch oscillation of elastic waves in the graded lattice of 3D-printed hollow elliptical cylinders
Hyunryung Kim, Xiaotian Shi, Eunho Kim +1
We study the Bloch oscillation of elastic waves in a chain composed of hollow elliptical cylinders (HECs). These HECs are 3D-printed in different wall thicknesses and are arranged…

Nonlinear Wave Propagation in 3D-Printed Graded Lattices of Hollow Elliptical Cylinders
Hyunryung Kim, Eunho Kim, Jinkyu Yang
We propose a 3D-printed graded lattice made of hollow elliptical cylinders (HECs) as a new way to design impact mitigation systems. We observe asymmetric dynamics in the graded HEC…
