Abstract: We present a onedimensional, multiscale massspring model to describe the response of vertically aligned carbon nanotube (VACNT) foams subjected to uniaxial, highrate compressive deformations. The model uses mesoscopic ...

Abstract: We study the elastodynamics of a periodic metastructure incorporating a defect pair that enforces a paritytime (PT) symmetry due to judiciously engineered imaginary impedance elements—one having energy amplification (gain) ...
