The vibration attenuation characteristics of a metamaterial plate were investigated theoretically and experimentally with a 2-dimensional periodic array of resonators (mass-beam) attached to a thin homogeneous plate.The sensitivity analysis of the band gap frequency range took into account the uncertainties of all the design parameters of the metamaterial plate. The theoretical approach used the finite element method (FEM) to compare the predicted band gaps with those derived from infinite and finite models of the metamaterial.An original automatic method is proposed to detect the frequency ranges of band gaps in finite metamaterial based on the behavior of the corresponding bare plate. Directional plane wave excitation and point force exci...
