Fracturing Behavior and Size Effect of Discontinuous Fiber Composite Structures with Different Platelet Sizes
Seunghyun Ko, Jinkyu Yang, Mark E. Tuttle +1
This study investigates the mode I intra-laminar fracture and size effect in Discontinuous Fiber Composites (DFCs). Towards this goal, the results of fracture tests on geometricall…
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…
Experimental demonstration of topological waveguiding in elastic plates with local resonators
Rajesh Chaunsali, Chun-Wei Chen, Jinkyu Yang
It is recent that the emergence of topological insulators in condensed matter physics has inspired analogous wave phenomena in mechanical systems, mostly in the setting of discrete…
Origami-based impact mitigation via rarefaction solitary wave creation
Hiromi Yasuda, Yasuhiro Miyazawa, Efstathios G. Charalampidis +3
The principles underlying the art of origami paper folding can be applied to design sophisticated metamaterials with unique mechanical properties. By exploiting the flat crease pat…
