Architected Lattices with Adaptive Energy Absorption
Yifan Wang, Brian Ramirez, Kalind Carpenter +3
Energy absorbing materials, like foams used in protective equipment, are able to undergo large deformations under low stresses, reducing the incoming stress wave below an injury or…
Shape-morphing architected sheets with non-periodic cut patterns
Paolo Celli, Connor McMahan, Brian Ramirez +5
We investigate the out-of-plane shape morphing capability of single-material elastic sheets with architected cut patterns that result in arrays of tiles connected by flexible hinge…
Intrinsically polar elastic metamaterials
Osama R. Bilal, Roman Süsstrunk, Chiara Daraio +1
The ability to design and fabricate materials with tailored mechanical properties, combined with immunity to damage, is a frontier of materials engineering. For example, materials…
Generation of Sound Bullets with a Nonlinear Acoustic Lens
Alessandro Spadoni, Chiara Daraio
Acoustic lenses are employed in a variety of applications, from biomedical imaging and surgery, to defense systems, but their performance is limited by their linear operational env…
Tunable frequency band-gap and pulse propagation in a strongly nonlinear diatomic chain
E. B. Herbold, J. Kim, V. F. Nesterenko +2
One-dimensional nonlinear phononic crystals have been assembled from periodic diatomic chains of stainless steel cylinders alternated with Polytetrafluoroethylene (PTFE) spheres. W…
Influence of Controlled Viscous Dissipation on the Propagation of Strongly Nonlinear Waves in Stainless Steel Based Phononic Crystals
E. B. Herbold, V. F. Nesterenko, C. Daraio
Strongly nonlinear phononic crystals were assembled from stainless steel spheres. Single solitary waves and splitting of an initial pulse into a train of solitary waves were invest…
Anomalous wave reflection from the interface of two strongly nonlinear granular media
V. F. Nesterenko, C. Daraio, E. B. Herbold +1
Granular materials exhibit a strongly nonlinear behaviour affecting the propagation of information in the medium. Dynamically self-organized strongly nonlinear solitary waves are t…
Strongly nonlinear waves in a chain of Teflon beads
C. Daraio, V. F. Nesterenko, E. Herbold +1
One dimensional "sonic vacuum" type phononic crystals were assembled from a chain of Teflon spheres with different diameters in a Teflon holder. It was demonstrated for the first t…
