Main Information

This talk will overview recent research activities in the fields of phononics, acoustic, and mechanical metamaterials in the MetaMechanics group at the University of Groningen. The current research directions of the group are twofold.

The first direction is toward understanding fundamental relations between the geometric topology of meta-structures and the material properties of their constituents. To this purpose, we have studied the effects of secondary relaxation of viscoelastic polymers on wave propagation and attenuation in phononic plates, which exhibit one of the two key wave control mechanisms at different ranges of sound and ultrasound frequencies [1]. We showed that in the case of overlapping secondary transition zones in a polymer, the dynamic behavior of the corresponding phononic plates cannot be described by using time-temperature superposition principle and traditional viscoelastic mechanical models. Similar situation can occur in additively manufactured polymeric meta-structures [2], the characterization of which is the subject of the ongoing research.

The second research direction is aimed at developing application-oriented metamaterial designs. Recent results are linked to mechanical and acoustic metamaterials. For mechanical metamaterials, we have developed automated strategies for programmable shape-morphing of flat and tubular meta-structures [3,4], used triply periodic meta-structures to develop stress-shielding-free mandibular implants, adopted kirigami arrays for distributed actuation systems in adaptive optics [5], and applied honeycomb and auxetic surface patterns to flapping wings with the aim to control their aerodynamic and aeroacoustic characteristics [6,7]. For acoustic metamaterials, we designed configurations inspired by space-filling curves [8] and used them to construct a meta-panel that can effectively attenuate low-frequency sound [9].
