Dispersion analysis of the hourglass-shaped periodic shell lattice structure

The concept utilizes elastic wave resonances to form constructive or destructive interference, which creates ranges of frequencies at which waves are either allowed to propagate (pass bands) or blocked in one (stop bands) or multiple directions (complete band gaps (BGs)). The bandgap depends on the geometric configuration and material of the unit cell, stiffness properties of the periodic structure as well as host matrix of the resonating mass, which has been exploited in designing the metamaterial. The unit cell is designed with the hourglass lattice integrated with a cubic resonating mass at the center which helps to induce ultrawide bandgaps with effective mechanical properties. Using various parametric combinations, a detailed bandgap analysis was performed for a spherical and parabolic hourglass-based matrix. After numerical simulation, additive layer manufacturing (3Dā printing) and experimental testing are carried out to evaluate the system and reveal the underlying physics responsible for its unique dynamic behaviour.
