Time-periodic stiffness modulation in elastic metamaterials for selective wave filtering: theory and experimental investigations
Giuseppe Trainiti, Yiwei Xia, Jacopo Marconi +2
We report on broadband-to-narrowband elastic wave filtering resulting from time-periodic modulation of the stiffness of a one-dimensional elastic waveguide. Time modulation produce…
Optical evaluation of the wave filtering properties of graded undulated lattices
Giuseppe Trainiti, Massimo Ruzzene
We investigate and experimentally demonstrate the elastic wave filtering properties of graded undulated lattices. Square reticulates composed of curved beams are characterized by g…
A Bloch-based procedure for dispersion analysis of lattices with periodic time-varying properties
Javier Vila, Raj Kumar Pal, Massimo Ruzzene +1
We present a procedure for the systematic estimation of the dispersion properties of linear discrete systems with periodic time-varying coefficients. The approach relies on the ana…
Optical Measurement of In-plane Elastic Waves in Mechanical Metamaterials Through Digital Image Correlation
Marshall Schaeffer, Giuseppe Trainiti, Massimo Ruzzene
We report on a Digital Image Correlation-based technique for the detection of in-plane elastic waves propagating in structural lattices. The experimental characterization of wave m…
Non-Reciprocal Wave Propagation in Spatiotemporal Periodic Structures
Giuseppe Trainiti, Massimo Ruzzene
We study longitudinal and transverse wave propagation in beams with elastic properties that are periodically varying in space and time. Spatiotemporal modulation of the elastic pro…
Wave Propagation in Undulated Structural Lattices
Giuseppe Trainiti, Julian J. Rimoli, Massimo Ruzzene
This work investigates wave propagation in undulated square structural lattices. The undulated pattern is obtained by imposing an initial curvature to the lattice's elements. The s…
