Beyond von Mises Truss Models: Emergent Bistability in Mechanical Metamaterials
Md Nahid Hasan, Taylor E. Greenwood, Sharat Paul +4
We observe and analyze the phenomenon of bistability emergent from cooperative stiffening in hyper-elastic metamaterials. Using experimental and numerical results of identical geom…

Nonlocality-enabled inverse design of Dirac-type and higher-order degeneracies for traveling and evanescent waves in phononic crystals
Sharat Paul, Md Nahid Hasan, Pai Wang
We propose complete tailoring procedures with analytical precision for band degeneracies in one-dimensional (1D) nonlocal phononic crystals, focusing on the role of beyond-nearest-…

Harmonically Induced Shape Morphing of Bistable Buckled Beam with Static Bias
Md Nahid Hasan, Sharat Paul, Taylor E. Greenwood +3
We investigate the effect of a constant static bias force on the dynamically induced shape morphing of a pre-buckled bistable beam, focusing on the beam's ability to change its vib…
