Wave propagation in auxetic tetrachiral honeycombs

This was an output from EU FP6 project NMP-CT-2005-013641 CHISMACOMB. This paper reported a numerical and experimental investigation on the flexural wave propagation properties of novel honeycombs with tetrachiral topology. The tetrachiral honeycomb configuration provides a new interesting platform for novel sandwich structures with negative Poisson’s ratio, where dome-shaped and sinclastic curvatures are required to manufacture complex geometries, from air ducts, fuselage components, nacelle engines, and satellite antennas. This significant sensitivity versus the topology of the unit cell suggests potential use also in tuning band-gap structures, both in terms of passive design and active vibration control.
