Elastic Weyl points and surface arc states in 3D structures
Xiaotian Shi, Rajesh Chaunsali, Feng Li +1
The study of Weyl points in electronic systems has inspired many recent researches in classical systems such as photonic and acoustic lattices. Here we show how the Weyl physics ca…
Mechanical analogue of a Majorana bound state
Chun-Wei Chen, Natalia Lera, Rajesh Chaunsali +5
The discovery of topologically non-trivial electronic systems has opened a new age in condensed matter research. From topological insulators to topological superconductors and Weyl…
Gradient-index granular crystals: From boomerang motion to asymmetric transmission of waves
Eunho Kim, Rajesh Chaunsali, Jinkyu Yang
We present a gradient-index crystal that offers extreme tunability in terms of manipulating the propagation of elastic waves. For small-amplitude excitations, we achieve control ov…
Valley Anisotropy in Elastic Metamaterials
Shuaifeng Li, Ingi Kim, Satoshi Iwamoto +2
Valley, as a new degree of freedom, raises the valleytronics in fundamental and applied science. The elastic analogs of valley states have been proposed by mimicking the symmetrica…
Effect of the Thickness on the Fracturing Behavior of Discontinuous Fiber Composite Structures
Seunghyun Ko, James Davey, Sam Douglass +3
In this study, we investigate experimentally and numerically the mode I intra-laminar fracture and size effect of Discontinuous Fiber Composites (DFCs) as a function of the structu…
