Non-reciprocal flexural wave propagation in a modulated metabeam
Flexural wave propagation in an Euler–Bernoulli beam coupled to a set of spring–mass resonators is investigated in the presence of a pump wave in the form of a space–time modulation of the beamresonators coupling stiffness. A phase matching condition implies then that waves incident along or against the pump wave behave differently and gives rise in select frequency bands to one-way blocking an...
متن کاملA Topology-Based Mass/Spring System
This paper presents how to design and implement a simple mass/spring system on a general-purpose topological structure. This way, topological inquiries or changes can be handled robustly so that the mesh remains consistent and a manifold.
متن کاملPeriodic Motion of a Mass-Spring System
The equations of planar motion of a mass attached to two anchored massless springs form a symmetric Hamiltonian system. The system has a single dimensionless parameter L, corresponding to the spacing between the anchors. For L > 1, there is a stable equilibrium at which the springs are in tension and lie on a line, but for L < 1, this equilibrium has both springs in compression, and is unstable...
متن کاملNon-reciprocal wave propagation in modulated elastic metamaterials.
Time-reversal symmetry for elastic wave propagation breaks down in a resonant mass-in-mass lattice whose inner-stiffness is weakly modulated in space and in time in a wave-like fashion. Specifically, one-way wave transmission, conversion and amplification as well as unidirectional wave blocking are demonstrated analytically through an asymptotic analysis based on coupled mode theory and numeric...
